Question

X to the 2nd power = -169 what is x

Answer 1

Given:

`x^2=-169`

To solve for x, we need to cancel the exponent. To cancel a square, we need to square root both sides.

`√(x^2)=√(-169)`

The square root of 169 is 13, but since it is negative, we need to put the imaginary unit,
`i`, in front of the answer. (
`i=√(-1)`)

Simplify.

`x=13i`

If you have not learned imaginary numbers or the imaginary unit yet, you could say that
`x=√(-169)`.
