Answer:

x = 4

Step-by-step explanation:

[tex] {5}^{x - 2} = 25[/tex]

Create equivalent expressions in the equation that all have equal bases.

5^x−2=25

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

x −2 = 2

Move all terms not containing

x to the right side of the equation.

Add 2 to both sides of the equation.

x =2 + 2

Add 2 and 2.

x = 4
