Solving for Unknown Exponents

Sometimes, you will be given an equation and be asked to solve for an exponent. For example:

It may seem obvious, but your solution is not complete. To solve completely, you must write 16 as a power of 4, so both sides of the equation have the same base.

Now, since the bases are equivalent, the exponents are equivalent. So we know that x = 2.
