ME AJUDEM POR FAVOR!!!

Answer 1

Explicação passo-a-passo:

(3/4)³= 3³/4³

(3/4)³=(3.3.3)/(4.4.4)

(3/4)³=27/64

====

(-2/3)³=(-2/3).(-2/3).(-2/3)

(-2/3)³=-8/27

=====

(-4/7)¹=-4/7

=====

(2/3)-²=(3/2)²=3²/2²

(2/3)-²=(3.3)/(2.2)

(2/3)-²=9/4

======

(2/3)-¹=(3/2)¹= 3/2

====

(-3/4)-³=(-4/3)³

(-3/4)-³=(-4/3).(-4/3).(-4/3)

(-3/4)-³=-64/27

====

(1/5)-¹=(5)¹= 5

(1/3)-²=(3)²=3.3

(1/3)-²=9
