Question

Rewrite using a single positive exponent. 7^9 x 7^-3

Answer 1

When you multiply you add the exponents, so 7^9*7^-3=7^6

Answer 2

Answer:

$7^{6}$

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$  ⇔ $a^{(m+n)}$, thus

$7^{9}$ × $7^{-3}$

= $7^{(9-3)}$

= $7^{6}$
