Question

5.Calcule as Expressões Numéricas:

Answer 1

Resposta:

$A) (-9)^{2} = 81\\\\(+5)*(+16)=80$

$B) (-2)^{4} = 16\\\\(+16)*(-1) = -16$

$C) (-6)^{2} = 36\\\\(-7)^{2} +13^{0} = 49$

$D) 5^{2} = 25\\\\(-3)^{3} =-27\\\\(-4)^{2} = 16$

$E) -11^{2} = -121\\\\(-4) * (-5) = 20$

$F) (-6)^{2} = 36\\\\(-2)^{2} =4\\\\(-1)^{2} = 1$

$G) 7*(-2)^{2} = 7*4=28\\\\(-5)^{2} = 25$
