Question

Calcule o valor das expressões: (1/5)-² . (2/3)³ + 3-² .3⁵​

Answer 1

Resposta:

(1/5)⁻² . (2/3)³ + 3⁻² .3⁵​

5² . (8/27) + 3⁻²⁺⁵

25*8/27  +3³

25*8/27  +8

25*8/27  +8*27/27

=8 * (25+27)/27

=416/27 = 15,407...

Answer 2

Resposta:

o valor é: 929/27

Explicação passo-a-passo:

(5/1)² . 2³/3³ + (1/3)² . 3⁵

25/1 . 8/27 + 1/9 . 243/1

200/27 + 243/9 =

m.m.c (27,9)=27

200/27 + 729/27= 929/27

tá aí :)
