Question 32935: I asked these two questions but i did not quite understand how to work them out. Can some pls explain them a bit better that way i can work them out and understand them pls.
3 times Sqrt 13/3. The answer i got for this one was that there was no variable to solve for. Im not sure what that means or if its already in simplest form?

The other one was Sqrt 2 + Sqrt 2/49. I dint quite understand how to work the problem.

3*(sqrt(13/3)
rationalise my mutlipling with sqrt(3)on both the numerator and denominator which gives us
3 *sqrt(3) *sqrt(13)/3
sqrt(3) * sqrt (13)
Sqrt(13*3)
sqrt(39)
Sqrt(2) +sqrt(2/49)
sqrt(2)+sqrt(2)/7
{7sqrt(2)+sqrt(2)}/7
sqrt(2)(7+1)/7
8sqrt(2)/7
