the square root is same as exponent of (1/2) ... so divide the exponent in half to nearest integer , then leave the remainder inside square root \[\sqrt{x^{7}} = x^{7/2} = x^{3} x^{1/2} = x^{3} \sqrt{x}\]

\[\frac{ 7q^4 }{{\sqrt{q ^{15}}} }\] so now we're focusing on just q.\[\frac{ q^4 }{ q ^{\frac{ 15 }{ 2 }} }\]So now we have \[q ^{(15/2)4}= q ^{(15/2)(8/2)}= q ^{7/2}\] wecan also rewrite q under a radical. \[\sqrt{q ^{7}}\] putting it altogether, we would have \[\frac{ 7 }{ \sqrt{q ^{7}}}\] or you can write this as \[\frac{ 7 }{ q ^{7/2} }\]

Hope that's not too complicated! :(

never leave a square root in denominator either... \[\frac{1}{\sqrt{x}}*\frac{\sqrt{x}}{\sqrt{x}} = \frac{\sqrt{x}}{x}\]

Oh, in correlation to what @dumbcow was referring to, \[\frac{ 7 }{ \sqrt{q ^{7}} }*\frac{ \sqrt{q ^{7}} }{ \sqrt{q ^{7}} }=\frac{ 7\sqrt{q ^{7}} }{ q ^{7} }\] As he said,you can't have a radical in the denominator.

\[\frac{ 7q ^{4} }{ \sqrt{q ^{8}}*\sqrt{q ^{7}} }\] = \[\frac{ 7 }{ \sqrt{q ^{7}} }= \frac{ 7 }{ q ^{3}*\sqrt{q} }\] \[ans*\frac{ \sqrt{q} }{ \sqrt{q} }\] =\[\frac{ 7\sqrt{q} }{ q ^{3}*q }=\frac{ 7\sqrt{q} }{ q ^{4} }\]
