-7²=
(-7)²=
-2⁴=
(-2)⁷=
-4³=
(-4)³=
-(+2)³=
-(-3)⁴=​

Answer 1

Resposta:

-7²=  7 x 7 = - 49

(-7)²=  -7 x -7 = 49

-2⁴=  2 x 2 x 2 x 2 = - 16

(-2)⁷=  -2 x -2 x -2 x -2 x -2 x -2 x -2 = - 128

-4³=  4 x 4 x 4 = - 64

(-4)³=  -4 x -4 x -4 = - 64

-(+2)³=  -(2 x 2 x 2) = -(+8) = -8

-(-3)⁴=​ - (-3 x -3 x -3 x -3) = - (81) = - 81

Bons estudos.
