Answer:

225

Explanation:

All you have to do is plug in the numbers, it will look like this

(2(2)^2 * -1^3)^2

It looks weird but trust me

Ok so first you have to mutiply 2*2 whitch is 4

(4^2 * -1^3)^2

now what is the 1 with the exponet of 3? It will stay at -1

(4^2 * -1) ^2

what is 4^2? it is the same a 4*4

whitch is 16

(16-1)^2

16-1?

(15)^2, same thing as 15*15

whitch is 225

makingn 255 your answer
