Answer 1

a)(+12)^2=144
b)(+15)^1=15
c) (+8)^3=512
d) (-19)^2=361
e) (-3)^5= -243
f) (-2)^8=256
g) (-1)^4=1
h) (+1)^6=1
i) (-3)^4=81
j)(-2)^6=64
k)(-7)^3= -343
l) (-11)^2=121
m) (-5)^3= -125
n) (-2)^3= -8
o)(-5)^3•(+2)^3=
-125+8= -117

p)(+7)^4•(-9)^4=
7^4•9^4=
(7•9)^4=63^4

r)(+12)^5•(-3)^5=
12^5•(-3^5)=
-(12•3)^5= -36^5

q)(-5)^3•(-2)^3=
(-125)•(-8)=1000

s) (-15)^3:(3)^3=
-15^3:3^3=
-(15:3)^3=
-5^3= -125

t)(-42)^5:(+7)^5=
-42^5:7^5=
-(42:7)^5=
-6^5= -7776
