Recognize Power of 5: Recognize that 125 is a power of 5. 125 can be written as 5^3 because 5 * 5 * 5 = 125.Set Exponents Equal: Set the exponents equal to each other since the bases are the same. Since 5^(x+2) = 5^3, we can set x + 2 = 3 because if the bases are the same, the exponents must be equal for the two expressions to be equal.Solve for x: Solve for x. Subtract 2 from both sides of the equation x + 2 = 3 to isolate x. x + 2 - 2 = 3 - 2 x = 1

5^{(x+2)} = 125

Recognize Power of $5$ : Recognize that $125$ is a power of $5$ . $125$ can be written as $5^3$ because $5 \times 5 \times 5 = 125$ .
Set Exponents Equal: Set the exponents equal to each other since the bases are the same. $\newline$ Since $5^{x+2} = 5^3$ , we can set $x + 2 = 3$ because if the bases are the same, the exponents must be equal for the two expressions to be equal.
Solve for x: Solve for x. $\newline$ Subtract $2$ from both sides of the equation $x + 2 = 3$ to isolate $x$ . $\newline$ $x + 2 - 2 = 3 - 2$ $\newline$ $x = 1$
