The square root of 18 is not 6 it's 4.24264069\n\nThe square root of 36 is 6.

Well, the square root is 27i, that makes it easy, cause 3X3X3 = 27, so 3 to the 6th is 729, and i X i is -1, so the sixth root of -729 is 3i.

2^6 = 64\n4^-2 = 1/4^2 = 1/16 = 0.0625\n64 * 0.0625 = 4

it is 136641(square each digit of previous number and put them in order)\ne.g. 7*7=49\n     49--(4*4=16,9*9=81) so no. is 1681\ntherefore next no. is (1*1,6*6,8*8,1*1)=(1,36,64,1)=136641

Here : \n\n4^2x3-64 reads 4 squared times the cube root of 64.\n\n= 4x4 x (64)^1/3 = 4 x 4 x 4 = 4^3 = 64\n\nAND \n\n16^7/2 x 2^0 = ((4)^2)^7/2 x 1 = (4)^ (2 x 7/2) = 4^7\n\nCOMPRENDE` ?

4 and 64\nSQRT4 = 2\nSQRT64 = 8\n8 + 2 = 10\n64 - 4 = 60

64/x=8/100\n8x=6400\nx=800

true\n\nbecuase you know that the square root of 38 is between 6 and 7, because there squares are 36 and 42

Write the ratios as fractions:\n1 ... x\n-- = --\nx .. 64\n\nCross multiply:\nx² = 64\n\nTake the square root of both sides:\nx = ±8\n\nTechnically the answer is ±8, but given your answers, the correct answer is:\n\nB) x = 8

You can goto http://www.math.com 's square root calculator and figure out that it is about 20.78 so since an integer is a decimal-less number the answer would be between 20 and 21.\n\nShort of using the sqrt function of a calculator if you know that 20 squared is 400 and that is close to 43 you might then try squaring 21 and get 441 then realize 432's sqrt must be between 20 and 21.

Let's denote square root by sqrt for simplification.\n\nsqrt (32)= 4*sqrt(2)\n\nsqrt (98)= 7*sqrt(2)\n\nsqrt (50)= 5*sqrt(2)\n\nThe question is thus: \n4*sqrt(2)-7*sqrt(2)+5*sqrt(2) = what\n\nBy taking sqrt(2) as a common factor:\n\nsqrt(2)*(4-7+5) = what ------------ Distributive property \n\nThe numbers in bracket add to 2.\n\nTherefore the final answer is 2*sqrt(2)

because 56 is not an even root the best answer is=\n(n-squareroot of 56)(n+squareroot of 56). \nThe square root of 56 is 7.48331477355 if you need the exact number, but that's messy.
