Answer 1

Answer:

Step-by-step explanation:

e). (13^-3)^-2=13^(-3)(-2)

13^6=13^6

4,826,809

2). (-1/2)^-3÷(-1/2)^-4=(-1/2)^-3+4

(-1/2)^-3-(-4)=(-1/2)^-3+4

(-1/2)^-3+4=(-1/2)^-3+4

(-1/2)^1=(-1/2)^1

-1/2=-1/2

3). [(1/7)^5]^3=(1/7)^5×3

(1/7)^5×3=(1/7)^5×3

(1/7)^15=(1/7)^15

4). (7×8)^-3=7^(-3)×8^(-3)

(72)^-3=(7×8)^-3

72^-3=72^-3
