Root 64 is 8, if by root you mean the square root.

Then the problem become -square root 84(6+8) which

is the - square root of 84(14)

But square root of 84 is 2(square root of 21) so the final answer comes

from -2(square root 21)x14

which is -28square root (21)

Why is negativeroot not define?

The negative root is not defined because if you multiply two negative numbers together, the product is still positive. 2*2 =4 (-2)*(-2) =4 So, there is no real answer to the square root of a negative number. In higher math however, the square root of negative one is actually defined as i. The set of i is a set of imaginary numbers, and they have some special properties.
