do you mean rationalize the denominator?
OpenStudy (anonymous):
?? sry
OpenStudy (anonymous):
what does it mean "simplify"?
OpenStudy (anonymous):
sqrt of 7 divide 10 i think
OpenStudy (anonymous):
maybe you are supposed to day
\[\sqrt{\frac{7}{10}}=\frac{\sqrt{7}}{\sqrt{10}}\]
\[=\frac{\sqrt{7}}{\sqrt{10}}\times \frac{\sqrt{10}}{\sqrt{10}}\]
\[=\frac{\sqrt{70}}{10}\]

That looks right, but the answer wasn't what it was looking for. Says "Recall that the square foot of a quotient is the quotient of the square roots."
OpenStudy (anonymous):
yes that was step one
OpenStudy (anonymous):
oh, lol ;)
OpenStudy (anonymous):
\[\sqrt{\frac{7}{10}}=\frac{\sqrt{7}}{\sqrt{10}}\] square root of quotient on the left, quotient of square roots on the rigth

forgive me... I'm an english student stuck in an algebra class!!

OpenStudy (anonymous):
