Hi, there. I'm happy to help with this.

I give a complete solution in the attached pdf.

There are some tricky concepts involved here. At Magoosh (https://gmat.magoosh.com/plans), we have well over 200 video lessons explaining all the difficult math & verbal concepts you will need on the GMAT. If you want to learn more about simplifying radicals and multiplying by the conjugate, my recommendation would be check out Magoosh.

Let me know if you have any further questions.

Mike :)

Is the answer...6?
I'm really old, but I'll never be too old to become more educated.
