Answer 1

Resposta:

a) 1/32

b) 1/144

c) 11^6

d) 625

e) 1/648

f)  (1/25)^4

g) 256

h) 243

i) 1/784

Explicação passo-a-passo:

a) (1/2)^2 x (1/2)^3 = 1/4 x 1/8 = 1/32

b) (1/4 x 1/3) = (1/12)^2 = 1/144

c) (11^(6-3)) = (11^3)^2 = 11^6

d) 5^4 = 625

e) 3^3 = 27^-2 =  (1/27)^2 = 1/648

f) 0,2 = 2/10 = (1/5)^-2 = 5^2 = 25^-4 = (1/25)^4

g) 4^6-2 = 4^4 = 256

h) 3^2-(-3) = 3^2+3 = 3^5 = 243

i)

7^-2 = (1/7)^2 = 1/49

(7-3)^2 = 4^2

1/49 / 16 = 1/49 x 1/16 = 1/784
