Question

Calcule o valor de cada potência
A (-8)elevado a 2
B (-4)elevado a 3
C 2elevado a 8
D 3elevado a 6

Answer 1

A (-8)² = -8.-8 = +64

B (-4)³ = -4.-4.-4 = -64

C 2⁸ = 2.2.2.2.2.2.2.2 = 256

D 3⁶ = 3.3.3.3.3.3 = 729

Answer 2

A= -8 x-8= 64
B= -4 x -4 x -4=64
C= 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2= 256
D= 3 x 3 x 3 x 3 x 3 x 3=729
