Answer 1

CALCULAR AS EXPRESSÕES:

A) 2³ = 8

B) 2 ELEVADO A ZERO = 1

C) (-2)³ = -8

D)2 elevado a -5 = 1/2 evelado a 5 = 1/32

E) 2/5 elevado a 3 = 8/125

F) (2³)² = 2 elevado a 6 = 64

H) (3/3) elevado a 4 = 1

I) (0,5) = (1/2)³ = 1/8

J) (-1/10)³ = -1/1000

L) 1+0,1681 = 1,1681

M) 1/4+125 - 1/16 = 4+2000 - 1 /16 = 2003/16

N) -(-1) =1 

O) 2 elevado a -3 = 1/2 elevado a 3 = 1/8 + 1/64 = 8+1/64 = 9/64

P) (0,3333333)³ = (1/3)³ = 1/27 + 3 = 27+ 81/27 = 108/27 = 4.
