This math topic involves using logarithms to solve exponential equations where the exponents are missing, and the answers must be expressed in decimal form. Each problem requires students to find the value of 'x' for equations like `a^x = b`, with multiple-choice answers provided. This forms part of a broader introduction to logarithms. The focused skill is the application of logarithms to decipher exponents when the base and the result of the exponentiation are known.
