Answer:

x = -6.

Explanation:

When typing questions to be answered, always specify if the equation required the "^" exponent like how this person did.

Got a lot of these firsthand that didn't have the exponent marker and gave people incorrect answers.

The equation seems to be

1
-------- = 5 ^ (x + 4)
25

In that case, this is the solution, stept by step:

1) factor 25: 25 = 5^2

1
=> ----------- = 5^(x + 4)
5^2

2) invert 5^2

=> 5^(-2) = 5^(x+4)

3) Given that the bases are equal, the exponents also have to be equal:

=> - 2 = x + 4

3) transpose +4:

=> - 2 - 4 = x

=> x = - 6

Answer: - 6
