    simplifying fractions under a radical

    square root of 49/50

    49/50 are both under the radical, i dont know how to make a radical sign in this text editor

    the 49 obviously cancels out to 7, but where do i go from there?

    Hey snazzy.

    If you have windows then go to run and type charmap and press enter. Then scroll down until you see a square root sign in your font and then select, copy, and paste into your document.

    Re: simplifying fractions under a radical

    \sqrt{ \frac{49}{50}}= \frac{ \sqrt{49}}{ \sqrt{50}}= \frac{ \sqrt{7^2}}{ \sqrt{2\cdot5^2}}= \frac{7}{5 \sqrt{2}} \cdot \frac{ \sqrt{2}}{ \sqrt{2}}= \frac{7 \sqrt{2}}{10}
