Adding and Subtracting Rational Expressions

What is the first step in solving exponential equations using logarithms when a common base is not applicable?

• Isolate the exponential expression

• Take the logarithm of both sides

• Check for extraneous solutions

• Expand the logarithms using the power rule

What rule allows you to move the exponent in front of the logarithm?

• Chain rule

• Power rule
