Question

Solve each log equation for real solutionslogx 81 =2

Answer 1

x=9. The log value is the same as the base in exponential form and the value on the opposite side of the equal sign is the exponent. So you can rewrite the equation as, x^2=81. 9^2=81 so x=9

Answer 2

x=9

Explanation:

You would change it to x^2 = 81 which is 9.
