im really stuck on my surds homework, i just need help on finding out how to do it.
Express ^63/3 + 14/^7 in the form n^7, where n is an integar.
Hello
Something like this?
$\displaystyle \frac{\sqrt{63}}{3} + \frac{14}{\sqrt{7}}$
$\displaystyle =\frac{\sqrt{9}*\sqrt{7}}{3} + \frac{14\sqrt{7}}{7}$
$\displaystyle =\frac{3\sqrt{7}}{3} + 2\sqrt{7}$
$\displaystyle = \sqrt{7} + 2\sqrt{7}$
$\displaystyle = 3\sqrt{7}$
Does that help, can you follow the steps?
