F) [(+5) . (-2)]2 =
​

Answer 1

Resposta:

$A)[(-2).(+3)]^{5} \\(-6)^{5} \\-7776$

$B) [(+5) . (-7)]^{3} \\(-35)^{3} \\-42875$

$C) [(-7) . (+4)]^{2} \\(-28)^{2} \\+784$

$D) [(+3) . (+5)]^{2} \\(15)^{2} \\+225$

$E) [(-4) .(+6)]^{3} \\(-24)^{3} \\-13824$

$F) [(+5) . (-2)]^{2} \\(-10)^{2} \\+100$
