[tex] {a}^{n} \times {a}^{m} = {a}^{n + m} [/tex]
[tex] {3}^{4} \times {3}^{1} = {3}^{5} = 243[/tex]
[tex] {2}^{ - 5} \times {2}^{3} \\ ({ \frac{1}{2} })^{5} \times {2}^{3} = \frac{1}{32} \times 8 = \frac{1}{4} [/tex]
[tex] {2}^{ - 2} \times {2}^{ - 3} \\ ({ \frac{1}{2} })^{2} \times ( { \frac{1}{2} })^{3} = \frac{1}{4} \times \frac{1}{8} = \frac{1}{32} [/tex]
