Answer 2

We know that when two numbers are multiplied then their powers will get added and when two numbers are subtracted then their powers will get divided.

According to the question,

5^x × 5^8 = 5^-3

or, 5^x+8 = 5^-3

or, x + 8 = -3 [the numbers get cancelled]

or, x = -3 - 8 [transposition method]

or, x = -11

Answer:

The value of x is -11 .
