no solution because squareing a number makes it positive (except for 0, squaring it results in 0)

the answer is undefined
(if you know complex number then the answer is x=13i)

Answer:

Option A is correct

Undefined

Explanation:

Given that:


x^2=-169

Taking square root both sides we have;


√(x^2)=√(-169)


x = \pm √(-169)

There are no real solution but rather than there are two complex number i,e 13i, -13 i

Therefore, the value of x are undefined.
