Answer 1

Answer:

(1/-7)³= (-7)³

(-7)^x*(-7)³=7⁸

(7) ki power X+3=7⁸

from 7 to7 cut then

X+3=8

X=8-3

X=5

Answer 2

Answer:

5

Step-by-step explanation:

${( - 7)}^{x} \times { (\frac{1}{ - 7} )}^{ - 3} = {7}^{8}$

${( - 7)}^{x} \times {( - 7)}^{3} = {7}^{8}$

Since, the numbers are equal. We can equate the powers.

x + 3 = 8

x = 8 - 3

x = 5
