How to do this, thank you

Step-by-step explanation:

Power rule: you multiply the exponent.

Think of it this way: . In this case,

At this point our original number is  with 15 2s

Which is, by definition,

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
