Answer 1

Vai da seguinte forma:

A) (-3)² = (-3)(-3) = 9

B) 6⁵ = 6 × 6 × 6 × 6 × 6 = 7.776

C) 10¹⁵ = 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 = 1.000.000.000.000.000

D) (3⁷)² = (3 × 3 × 3 × 3 × 3 × 3 × 3)² =

2187² = 2.187 × 2.187 = 4.782.969

E) (0,4)⁴ = (0,4)(0,4)(0,4)(0,4) = 0,0256

F) (-0,28)¹ = - 0,28

G) (-12)⁵ = (-12)(-12)(-12)(-12)(-12) = -248.832

H) (2⁹)⁰ = 1

I) 2-⁵ = 1 ⁵ = 1 × 1 × 1 × 1

2 2 2 2 2

× 1 = 1

2 32

J) (2³)-³ = (2 × 2 × 2)-³ = 8-³ =

1 × 1 × 1 =

8 8 8
