Learn how to solve exponential equations by getting the bases to match and then setting the exponents equal to each other. For example, 8 and 16 could both be reduced to base 2, or 2^3=8 and 2^4=16, so you can use that to solve some exponential equations. If there is NO common base, then you could need to use a logarithm, which is covered in OTHER videos. Hope this helps!
