What is the solution to log sub 5 of open paren x plus 30 close paren is equal to 3 ?

Rewrite the logarithmic equation in exponential form: x + 30 = 5³ = 125. Subtract 30 from both sides to get x = 95. This is valid because the logarithm’s input, x + 30, is positive; 95 + 30 = 125. The correct choice is x is equal to 95.
