\[\frac{ x \frac{ 7 }{ 2 } }{ x \frac{ 2 }{ 5 } }\]

Are the fractions exponents?

I think I'm supposed to subract 7-2 and 2-5 which would equal \[x\frac{ 5 }{ 3 }\]

yes they are exponents.

\( \Large {\dfrac{ x ^{\frac{ 7 }{ 2 }} }{ x ^{\frac{ 2 }{ 5 } }}}\) Use the rule: \( \dfrac{x^m}{x^n} = x^{m - n} \) Since the exponents are fractions, you need a common denominator to subtract them.

guys is it just me or is latex not showing up?

\(\Large {\dfrac{ x ^{\frac{ 7 }{ 2 }} }{ x ^{\frac{ 2 }{ 5 } }}}\) \( \Large = x^{\frac{7}{2} - \frac{2}5} \) \( \Large = x^{\frac{5}{5}\frac{7}{2} - \frac{2}{2}\frac{2}5} \) \( \Large = x^{\frac{35}{10} - \frac{4}{10}} \) \( \Large = x^{\frac{31}{10}} \)
