Exponential functions can be represented in many different
ways by changing the base.
Example One
Express in terms of a power with a base of 2.
a) 8
b) 43
c) (√16)(5√32)3
d) 14

One way to solve an exponential equation is to change
the base of one or more exponents so that they all
have the same base. Then, equate the exponents and
solve.
Example Two
Solve each equation by changing the base.
a) 4x + 5 = 64x
b) 42x = 8x - 3
