Answer:

sqrt of -8

Step-by-step explanation:

In order to isolate W, do the opposite of PEMDAS. So first we should do the addition/subtraction, then the multiplication/division, then the exponent.

The addition:

2w^2 - 16 = -32

⬇️

2w^2 = -16
(Added 16 to both sides)


Division:

2w^2 = -16

⬇️

w^2 = -8
(divided out the 2)

Exponent:

w^2 = -8

⬇️

w = sqrt of -8
