What is the exact value of 4q^6 / sqrt(q^21)
\[\frac{4q^6}{\sqrt{q^{21}}}=\frac{4q^6}{(q^{21})^{\frac{1}{2}}}=\frac{4q^6}{q^{\frac{21}{2}}}\]Then,\[=4(q^{6-\frac{21}{2}})=4q^\frac{-9}{2}=\frac{4}{\sqrt{q^9}}\]
there is no answer like that.
it could be written in an equivalent form tho
is it, 4 sqrt (q) / q^5
yeah. I guess they don't want a square root appearing in the denominator.
nope, can I ask you another one?

The length of one side of a square can be determined by square rooting the area. Suppose the area of a square picture frame is represented by 1620v^9. Determine the exact length of one side of the picture frame.
just take the square root of the given area:\[\sqrt{1620v^9}\]
do you know how to do that?
\[\sqrt{81*4*5*v^8*v}=18v^4\sqrt{5v}\]
oooh thanks ! i'm doing a test on virtual school and some questions are confusing me.. like a lot
