Verified answer

√63 = √9 * √7 = 3√7. So, (√63)/3 = √7.

To simplify 14/√7, multplify numerator and denominator by √7. This gives you (14√7)/7 = 2√7.

So, your equation equals √7 + 2√7 = 3√7

n = 3.

get them to have the same denominator : 3 root 7

add the numerator

simplify

multiply both denominator and numberator by root 7

** im assuming that only 63 is rooted and not 63/3 (in the question)

n=15

(63^.5)/3 + 14(7^.5)

= (9^.5)(7^.5)/3 + 14(7^.5)

=3(7^.5)/3 + 14(7^.5)

= 15(7^.5)
