Exponential Equations and Factorization

The video tutorial explains how to solve exponential equations by using like bases. It demonstrates the process with two examples: one involving the equation 27^x = 2187 and another with (1/16)^x = 32. The tutorial emphasizes the importance of rewriting both sides of the equation with the same base, using prime factorization, and applying the rule that if the bases are the same, the exponents must be equal. The video also covers handling fractional bases and negative exponents.

What is the first step in solving exponential equations using like bases?

• Divide the exponents

• Multiply the bases

• Add the exponents

• Convert both sides to the same base

In the equation 27^x = 2187, why can't we use 27 as a base for 2187?
