b]6^ -1
c]123^ 0
d]1^ 87
e] [5/8]^2
f][-9]^-2
g][0,0012]^ 1
h][-4]^2
i]-3^2
j] [7/4]^-2
k][-15/11]^0
l][-7]^3

Answer 1

Resposta:

12^ 1= 12

b]6^ -1=0,16

c]123^ 0 = 1

d]1^ 87 = 1

e] [5/8]^2 = 0.4

f][-9]^-2 = 0.0123

g][0,0012]^ 1= 0.0012

h][-4]^2= =16

i]-3^2==-9

j] [7/4]^-2=3.06

k][-15/11]^0 = 1

l][-7]^3 = -343
