Question

URGENTE PFVRRRRRRRRRR

Answer 1

Resposta:

Explicação passo-a-passo:

2.-1/2 + 2/3 = -2/2 + 2/3 = -1 + 2/3 = -3 + 2/3 = -1/3

b)-5^2 + 2.-5 = 25 - 10 = 15

c) 3.-2.16/-2 + $\sqrt{16}$ = -96/-2 + 4 = -96/2 = -48

d) - (-10) + $\sqrt{-10^2 - 4.2.12}$ =

10 + $\sqrt{100 - 96}$ =  

10 + $\sqrt{4}$= 10 + 2 = 12
