The square root of minus 8 is equal to the square root of 8 times the square root of minus 1, or 2.8284i.

Expressed in root form, 5 sqrt(18) - 7 sqrt(8) = sqrt(2)

Such that the square root of 64 is equal to 8, sqrt(-64) is equal to 8 i, the letter i representing the square root of minus 1.

7.135 * * * * * sqrt(18)*sqrt(8) = sqrt(18*8) = sqrt(144) =12

Square root of 50 = 7.0710678118654755 Square root of 8 = 2.8284271247461903 So, round that off to 7.07, and 2.83 respectively. 7.07 - 2.83 = 4.24

If you mean 8i, i might be any variable, but it may also stand for the imaginary unit, sometimes defined as the square root of minus 1. In that case, 8i is 8 times the square root of minus 1.If you mean 8i, i might be any variable, but it may also stand for the imaginary unit, sometimes defined as the square root of minus 1.

square root of 8

The numbers are: 11 plus square root of 113 and 11 minus square root of 113

-4 plus/minus square root of 15.

The geometric mean of two numbers is the square root of their product. 18 x 8 = 144. The square root of 144 is 12. The geometric mean of 18 and 8 is 12.

Rounded to two decimal places, 8 sqrt(5) - 5 sqrt(54) = 18.85

4 sqrt(3) is. 8 of anything, minus 4 of the same thing, always leaves 4 of them.

It could be: 7/8 times 7/18 = 49/144 and its square root is 7/12

root 8 = root 4 x root 2 = 2 root 2, root 18 = root 9 x root 2 = 3 root 2; 2 root 2 x 3 root 2 = 6 x 2 = 12
