    Do you know how to turn the radicals into exponents?

    Use this rule\[\sqrt[n]{a}=a^{\frac{ 1 }{ n }}\] So you can change your numerator to \[7^\frac{ 1 }{ 3 }\] What would the denominator be?

    You have to take the small number from the radical and write it as an exponent.\[\frac{ \sqrt[3]{7} }{ \sqrt[5]{7} }=\frac{ 7^{\frac{ 1 }{ 3 }} }{ 7^{\frac{ 1 }{ 5 }} }=7^{(\frac{ 1 }{ 3 }-\frac{ 1 }{ 5 })}\]

    no. subtract 1/3 - 1/5 to get the final exponent
