The answer is 64. The cube-root of 512 is 8, 8 squared is 64.
As for example the square root of 64 is 8 but the cube root of 64 is 4
The answer is: 2.
The square root of 64 is 8. When you cube 8, you multiply it by itself three times, which equals 512. So, the cube of the square root of 64 is 512.
sqrt(16) = 4 4^(3) = 64 This can algebrically be shortened to 16^(3/2)
the cube root of 64 =4
The cube root of 512 is 8, the square root of 64 is 8, and the cube root of 343 is 7. Therefore, the expression simplifies to 8 divided by 8 times 7, which equals 7.
cube root of 64 = 4 4 x 4 = 16, and 16 x 4 = 64 4 cube = 64
64
Suppose x3 = -64 then x3 + 64 = 0So (x + 4)*(x2 - 4x + 16) = 0So x = 4 or x = 2 +/- 2i*sqrt(3) where i is the imaginary square root of -1.-4 * -4 * -4 = -64So cube root of -64 = -4
The square root of 16 is 4 and 4 cubed is 16x4=64
64 x 64 x 64 = 262,144√ 262,144 = 512Another way of arriving at this is to take the square root of 64, and cube it - 8 x 8 x 8 also = 512
