Question

sqrt (18x^7 over y^7)

Answer 1

\[\sqrt{18 x^7/y^7}\]

Answer 2

yep, that's it

Answer 3

rationalize the denominator in the expression. Assume all variable represent positive real numbers.

Answer 4

\[\sqrt{18x^7}/\sqrt{y^7}\times \sqrt{y^7}/\sqrt{y^7}\]

\[\sqrt{18x^7y^7} \over y^7\]

Answer 5

not it...

Answer 6

You can simplify further


\[\frac{\sqrt{18x^7y^7}}{y^7}\]


\[\frac{\sqrt{18}\sqrt{x^7}\sqrt{y^7}}{y^7}\]


\[\frac{3\sqrt{2}x^3\sqrt{x}y^3\sqrt{y}}{y^7}\]


\[\frac{3x^3y^3\sqrt{2xy}}{y^7}\]

Answer 7

Oops not done simplifying, you can simplify it even further to get


\[\frac{3x^3\sqrt{2xy}}{y^4}\]

Answer 8

you rock
