## Suggested Questions And Answer :

### solve the equation 3 log(base 2)(x-1)+log(base 2)4=5

The equation is equivalent to log (base 2 ) (X-1)^3 (4) = 5 , therefore , log(base 2)[X^3-3X^2+3X-1](4) = 5 , so , 2^5 = 4X^3-12X^2+12X-4 , we simplify a little bit more , then 32 = 4(X^3 - 3X^2 + 3X - 1) , then : 8 = X^3 - 3X^2 + 3X - 1 , putting the whole thing in standard form yuo get X^3 - 3X^2 + 3X - 9 = 0 , which you factorize in this way : X^2(X-3) 3(X-3) = 0 , (X-3)(X^2 +3) =0 , implying that X = 3 , X = 3^(1/2) i and X = -3^ (1/2)i three roots because is a third degree equation . Because we were asked to express the irrational answer rounded up to the third place , then we add : 3^(1/2) i = 1.732 i and its pair ( every irrational root comes in pairs ) would be -1.732 i

### solve -x-3y+4z=3, 5x-8y+5z=27,5x-2y+6z=1 with matrix

-x -3y +4z = 3 5x -8y +5z = 27 5x -2y +6z = 1 0 is neither + nor -, but I used +0 below to make the matrix line up better. The solution below looks a bit messy because fractions and exact numbers are being used.  If you use decimals the matrix will look prettier and won't have as many big numbers, but the answer will be slightly off due to rounding errors. matrix -1   -3   +4   |   +3 +5   -8   +5   |   +27 +5   -2   +6   |   +1 on the third row, subtract out the 2nd row -1   -3   +4   |   +3 +5   -8   +5   |   +27 +0   +6   +1   |   -26 multiply the top row by 5 -5   -15   +20   |   +15 +5   -8   +5   |   +27 +0   +6   +1   |   -26 in the top row, add the bottom row +0   -23   +25   |   +42 +5   -8   +5   |   +27 +0   +6   +1   |   -26 multiply the bottom row by -25 +0   -23   +25   |   +42 +5   -8   +5   |   +27 +0   -150   -25   |   +650 in the bottom row, add the top row +0   -23   +25   |   +42 +5   -8   +5   |   +27 +0   -127   +0   |   +692 multiply the top row by -127 +0   +2921   -3175   |   -5334 +5   -8   +5   |   +27 +0   -127   +0   |   +692 multiply the bottom row by 23 +0   +2921   -3175   |   -5334 +5   -8   +5   |   +27 +0   -2921   +0   |   +15916 add the bottom row to the top row +0   +0   -3175   |   +10582 +5   -8   +5   |   +27 +0   -2921   +0   |   +15916 multiply the middle row by -2921 +0   +0   -3175   |   +10582 -14605   +23368   -14605   |   -78867 +0   -2921   +0   |   +15916 multiply the bottom row by 8 +0   +0   -3175   |   +10582 -14605   +23368   -14605   |   -78867 +0   -23368   +0   |   +127328 add the bottom row to the middle row +0   +0   -3175   |   +10582 -14605   +0   -14605   |   +48461 +0   -23368   +0   |   +127328 multiply the top equation by -14605 +0   +0   +46370875   |   -154550110 -14605   +0   -14605   |   +48461 +0   -23368   +0   |   +127328 multiply the middle equation by 3175 +0   +0   +46370875   |   -154550110 +46370875   +0   +46370875   |   +153863675 +0   -23368   +0   |   +127328 add the top equation to the middle equation +0   +0   +46370875   |   -154550110 +46370875   +0   +0   |   -686435 +0   -23368   +0   |   +127328 divide the top equation by 46370875 +0   +0   +1   |   -154550110/46370875 +46370875   +0   +0   |   -686435 +0   -23368   +0   |   +127328 divide the middle equation by 46370875 +0   +0   +1   |   -154550110/46370875 +1   +0   +0   |   -686435/46370875 +0   -23368   +0   |   +127328 divide the bottom equation by -23368 +0   +0   +1   |   -154550110/46370875 +1   +0   +0   |   -686435/46370875 +0   +1   +0   |   -127328/23368 put the middle equation on top and the top equation on bottom +1   +0   +0   |   -686435/46370875 +0   +1   +0   |   -127328/23368 +0   +0   +1   |   -154550110/46370875 that's an answer, but the fractions on the right can be reduced. factor a 5 out from the top and bottom equations and a 4 out from the middle equation +1   +0   +0   |   -137287/9274175 +0   +1   +0   |   -15916/2921 +0   +0   +1   |   -30910022/9274175 factor a 23 out of all three equations +1   +0   +0   |   -5969/403225 +0   +1   +0   |   -692/127 +0   +0   +1   |   -1343914/403225 factor a 127 out of the top and bottom equations +1   +0   +0   |   -47/3175 +0   +1   +0   |   -692/127 +0   +0   +1   |   -10582/3175 Answer:  x = -47/3175, y = -692/127, z = -10582/3175 or, in decimal rounded to 4 places after the decimal Answer:  x = -0.0418, y = -5.4488, z = -3.3329

### Round off 9704.8372 to the: nearest thousand,nearest whole number , two decimal places , three significant figures

Nearest thousand is 10000, which is nearer than 9000. 9704.8372 is 704.8372 away from 9000; but only 295.1628 away from 10000. The guide is usually the digit in the hundred position: if it's 5 or more then we go up to the next thousand (9 to 10 in this case), otherwise we just take the thousand digit as it is (9 in this case). 7, the hundred digit, is bigger than 5, so we take 10 thousand. Nearest whole number is 9705, which is nearer than 9704, because the next digit 8 is bigger than 5 and the 4 in the ones position goes up to 5. 2 dec places is 9704.84, which is nearer than 9704.83. 3 sig figures is 9700. The 3 figures are 9, 7 and 0, because the zero is occupying a place separating it from the next digit 4, so it is significant. The 4 would make it 4 sig figures. The size of the number has to be preserved because, for example, 970 would not suggest the right number of thousands. Leading zeroes in whole numbers or mixed numbers are always discounted because they do not have any effect on the magnitude of the number.

### what is 259,345,278 rounded to the nearest ten thousandths

259,345,278 = 259,345,278.00000 I know it's all 0's after the decimal, but let's write it like this just for now:  259,345,278.abcde (that's so we can tell the difference between which 0 we're talking about) The 0 sitting on the d is in the ten thousandths place.  The next digit over is 0, which is less than 5, so the 0 in the ten thousandths place doesn't round up. Answer: 259,345,278.abcd = 259,345,278.0000 = 259,345,278 259,345,278 is already rounded to the nearest ten thousandth.
