Question

(-7)4
(-1)9
(-15)2
(+9)4
(-100)0​

Answer 1

Boa tarde !

Calculando a potência :

( - 7 )⁴ = ( - 7 ) × ( - 7 ) × ( - 7 ) × ( - 7 ) = 2401

( - 1 )⁹ = ( - 1 ) × ( - 1 ) × ( - 1 ) × ( - 1 ) × ( - 1 ) × ( - 1 ) × ( - 1 ) × ( - 1 ) × ( - 1 ) = - 1

( - 15 )² = ( - 15 ) × ( - 15 ) = 225

( + 9 )⁴ = ( + 9 ) × ( + 9 ) × ( + 9 ) × ( + 9 ) = 6561

( - 100 )⁰ = 1

Um grande abraço !
