Question

Sendo A= [(-25) : 5 + (-2) × (-5)]² e B= (+5)5 : (+5)⁴ × (+5), calcule o valor de B:A

Answer 1

Olá, (=^.^=)/

A) [(-25):5+(-2)×(-5)]² = 25
B) (+5)5:(+5)⁴×(+5) = 0,175

A) [(-25):5+(-2)×(-5)]² = 

[-5+10]^2 = 
[5]^2 = 
5.5 = 25

B) (+5)5:(+5)⁴×(+5) =

(5).5:(626).(5) = 
(5).0,007.5 =
0,035.5 = 0,175
