Write the log equation as an exponential equation. You do not need to solve for x: log(x^2+5x-18)=x+2

10ˣ⁺² = x² + 5x - 18

Step-by-step explanation: The base of the log becomes the base of the power, the right side of the equation becomes the exponent, and the result in the original equation moves to the other side.

Notice that we aren't given a base, so we know that we are

dealing with a common log which has a base of 10.
