Question

calcule as pontencias
a (+1)2 =?
b (-1)2 =?
c (+1)3 =?
d (+8)2 =?
e (-8)2 =?
f (+8)3 =?
g (+8)3 =?
h (-8)3 =?
​

Answer 1

a ) _ ( + 1 ) 2 = 1 x 1 = 1

b ) _ ( - 1 ) 2 = -1 x -1 = +1

c ) _ ( + 1 ) 3 = 1 x 1 x 1 = 1 x 1

d ) _ ( + 8 ) 2 = 8 x 8 = 16

e ) _ ( - 8 ) 2 = -8 x -8 = +16

f ) _ ( + 8 ) 3 = 8 x 8 x 8 = 16 x 8 = 128

g ) _ ( + 8 ) 3 = 8 x 8 x 8 = 16 x 8 = 128 [ você colocou a G e a F iguais ]

h ) _ ( - 8 ) 3 = -8 x -8 x -8 = +16 x -8 = -128
