alguém pode me ajudar? pfvr :(

Answer 1

Resposta

a) 2^3.2^1=2^4=16

b) 3^3:3^2.3^2

3^3-2.3^2=3^1.3^2=3^3=27

c) 2^3.5^3=(2.5)^3=10^3=1000

d) (2.3^2)^2=2^2.3^4=4.81=324

e) 15^3:3^3=(15:3)^3=5^3=125

f) (-4)^2:2^2=(-4:2)^2=(-2)^2=4

g) (3^3)^2=3^6=729

h)(-2^2)^3=(-2)^6=64

i)(-3^2)^2=(-3)^4=81

j) 4^3.1^2=64.1=64

l) (2.3)^3=2^2.3^3=4.27=108

m) (3^2.5.2)^3=3^6.5^3.2^3

( 729.125.8)
