lol ok |dw:1357604018475:dw|

3. kellyp73 Group Title

that is a q

4. mathmate Group Title

Is it: $$\huge (\frac{2q^4}{7})^4$$ ?

5. kellyp73 Group Title

yes how did you get that on there ?

6. mathmate Group Title

You type *( \huge(\frac{2q^4}{7})^4 *) except you replace the two * at the beginning and the end by \. Anyway, everything inside has to be raised to the fourth power, so it becomes: $$\huge(\frac{2^4(q^4)^4}{7^4})$$ = $$\huge(\frac{16q^{16}}{2401})$$

7. kellyp73 Group Title

i am really confused on all the 4 and the q

8. mathmate Group Title

Using the rules of exponents which says that $$\huge (\frac{a}{b})^c$$ = $$\huge \frac{a^c}{b^c}$$ And you can take it from here. (sorry, got to go)
