b) (+7/2)²=
c) (+3/4) elevado a -4=
d) (-12/13)¹=
e) (+5/9) elevado a -2=
f) (-3/5) elevado a -3=
g) (-2/5) elevado a -3=
h) (-5/4) elevado a -3=
i) (3/7) elevado a -2=
j) (-1/3) elevado a -2=

Answer 1

a) (-4)-²= (-1/4)²= 1/16

b)49/4

c) (3/4)-⁴=(4/3)⁴=256/81

d)-12/13

e)(5/9)-²=(9/5)²=81/25

f)(-3/5)-³=(-5/3)³=-125/27

g)(-2/5)-³=(-5/2)³= - 125/8

h)(-5/4)-³=(-4/5)³=-64/125

i) (3/7)-²=(7/3)²= 49/9

j)(-1/3)-²= (-3/1)²= (-3)²=+9
