Answer 1

                                  Olá, Eu Vou Ajudar vc!

a)(2/5)²

$(2,5) ^{2} = 2,5x2,5 = Resposta(6,25)$

b) (− 4/7)²

$(7/4)^{2} = 7^{2} /4^{2} = Resposta (49/16)$

c) (− 1/5)³

$Resposta:\\\\(-\frac{1}{5} )^{3} = \frac{1x1x1}{5x5x5} =(-\frac{1}{125} )$

d) 3/2²​

$(3/2) ^{2} = Resposta...(9/4)$

Bons Estudos!
