Simplify, express in simplest radical form: 3√(3/13)

[From: ] [author: ] [Date: 11-04-28] [Hit: ]
how did the 3* become a 3+???Please explain in detail as best as you can. I learn better with words than with numbers.Thank you so much!......
Okay this is what I have so far:
3*√(3/13)
=3*(√3/√13 *√13/√13)
=3*(√3√13/(√13)^2)
=3*√39/13

However, I'm not even sure if this is correct especially since everybody else is getting 3+√39/13
So I'd like to know if I worked this problem out correctly, if the answer is correct. If it's not correct and the other answer of 3+√39/13 is, then how did they get that answer? And most importantly, how did the 3* become a 3+???

Please explain in detail as best as you can. I learn better with words than with numbers.

Thank you so much!

You are correct that the answer is 3√(39)/13 since you rationalized the denominator and did the right algebra computation. I don't get why other people get +! Anyway...

I hope this helps!
