# EXPS 1 | Lesson 4 | Practice

Rewrite each of the equations below so that the bases are the same, and solve for $$x$$.

1.   $$2^x=32$$

2.   $$2^x=4^2$$

3.   $$4^{x-1}=16^3$$

4.   $$5^{\frac x2}=125$$

5.   $$3^{2-x}=27$$

6.   $$2^{x+2}=8^x$$

7.   $$2^{2x-1}=8^3$$

8.   $$2^{3x-1}=4^{x+3}$$

9. Go onto Khan Academy and take the unit test.
