RESOLVAM O DE OLHO NA PROVA P MIM PFVR

Answer 1

Olá,

1)

6ⁿ·3ⁿ = (6·3)ⁿ = (18)ⁿ = 18ⁿ


4·18ⁿ / 2·(6ⁿ·3ⁿ)
4·18ⁿ / 2·18ⁿ
4 / 2
2

Resposta: e)

2)

4^3/2 + 8^(-2/3) - 2^(-2)
(2^2)^3/2 + (2^3)^(-2/3) - 2^(-2)
2^(2·3/2) + 2^(3·(-2/3)) - 2^(-2)
2^(6/2) + 2^(-6/3) - 2^(-2)
2^3 + 2^(-2) - 2^(-2)
2^3 + 0
2^3
8

8/0,75
8/(3/4)
(8/1)/(3/4)
8/1 × 4/3
32/3

Resposta: e)
