remember, $$\dfrac{1}{x} \iff x^{-1}$$

3. keana

i know i have to eliminate the negative exponents but idk how

4. Jhannybean

Also, $$\dfrac{x^m}{x^n} = x^{m-n}$$

5. Jhannybean

Start by splitting up all the terms into like-term fractions: $\large \frac{15}{5} \cdot \frac{a^{-3}}{a^6} \cdot \frac{b^4}{b^{-2}} \cdot \frac{c^6}{c^4}$ now you subtract the power of the numerator from the denominator in each fraction, and simplify the constants.

6. Jhannybean

$\large \frac{15}{5} \cdot a^{-3-6} \cdot b^{4-(-2)} \cdot c^{6-4}$ Simplify this :)

7. keana

$15(1/a^3)b^4c^6$

8. Jhannybean

$\large a^{-3-6} \ne a^3$

9. keana

$5a^6(1/a^2)c^4$

10. Jhannybean

$\large a^{-3-6} = a^{-(3+6)} = ~?$

@keana ?
