I think you're supposed to multiply it by 12? But there seems to be other numbers multiplied by 12 that can make a perfect square too, but 12's the first one I thought of. So then I got

144, which equals 12. Is this right? What do I do next?

**Damon**, Saturday, May 9, 2009 at 6:40pmI can not read your symbol but assume it is a radical or sqrt sign

5 / sqrt 12

multiply top and bottom by sqrt 12

5 sqrt 12 / 12

= (5/12) sqrt (3*4)

= (10/12) sqrt 3

= (5/6) sqrt 3

**Angie**, Saturday, May 9, 2009 at 7:03pmhow did you get (10/12) sqrt 3?

**PsyDAG**, Monday, May 11, 2009 at 3:38pmFrom (5/12) sqrt (3*4) , 2 is sqrt of 4. Multiplying that by 5/12 gives you 10/12 times the remaining sqrt 3.

I hope that helps a little more. Thanks for asking.
