    alright \[\huge\rm \frac{ \sqrt[4]{9} \times \sqrt{9} }{ \sqrt[4]{9^5}} \] like this ?

    alright so you can convert root to exponent exponent rule \[\huge\rm \sqrt[m]{x^n} = x^ \frac{ n }{ m }\]

    m= root number n= exponent of base under the root

    how would you convert \[\sqrt[4]{9^1} = ???\] to exponent form ?

    |dw:1438952454421:dw| just apply the exponent look at the drawing just like i convertd 4th root of 9^5 to 9 to the 5/4 power

    yea now you have \[\huge\rm \frac{ 9^\frac{ 1 }{ 4 } \times 3 }{ 9^\frac{ 5 }{ 4 } }\] there are same bases at the numerator and t the denominator you need to apply quotient exponent rule \[\large\rm \frac{ x^m }{ x^n }=x^{m-n}\]
