simple way to solve this problem:2(-2)+5(-5)in2power

Question

2(-2)+5(-5)²

Answer 1

it appears the question is 2(-2) + 5(-5)²

 

Powers must be done first, then we can do all the multiplications, then the addition

 

2(-2) + 5(25)

 

-4 + 125

 

121 is the answer

Answer 2

I'm not sure if you mean [2(-2)+ 5(-5)]²  or you mean 2(-2) + [5(-5)]²

 

The first way is [-4+ -25]² = 841

The scond way -4 +(-25)² = 621

 

hope that helps!
