I don't understand how to work this math problem:
The square root of 5/7 + The square root of 7/5
How do you solve this type of problem?

-
rt = square root
rt5/rt7 + rt7/rt5
(rt7/rt7) (rt5/rt7) + (rt5/rt5) rt5 (rt7/rt5)
In the step above, you rationalize the denominators so that there are no roots in the denominator
rt35 / 7 + rt35 / 5
In the step above, the roots in the numerators were multiplied to simplify.
5rt35 / 35 + 7rt35 / 35
In the step above, by making the denominators equal using the least common multiple, you can now add the two fractions.
12rt35 / 35
