SOLUTION: {{{ sqrt ( 7 )/sqrt ( 2 ) + sqrt ( 2 )/sqrt ( 7 ) }}} = ??? I have tried multiplying both sides by {{{ sqrt ( 2 )/sqrt ( 2 )}}} , multiplying both sides by {{{ sqrt ( 7 )/sqrt (

Question 967658: = ???
I have tried multiplying both sides by , multiplying both sides by , and 3 other variations on the same theme without success. I know I am probably over complicating things, but I can't remember how to solve this. Please help!

(square root(7) / square root(2)) + (square root(2) / square root(7))=
first combine fractions over common denominator which is square root(14)
(square root(7)*square root(7)) + (square root(2)*square root(2)) / square root(14)=
(7 + 2) / square root(14) =
9 / square root(14) =
now multiply numerator and denominator by square root(14)
(9 * square root(14) / 14)
