<p>Thanks.</p>

<p>Hi xxeliza321xx,
I just sent you a PM with some notes to help you start tackling these radicals. I solved #1 and 2 for you. Hope my tips help.</p>

<p>Zenith is their anyway you can also send me the solutions/notes?</p>

<p>Ok thanks.</p>

<p>For anyone:</p>

<p>You have to multiply by the conjugate for the second one. :D</p>

<p>zenith could you pm me as well? thanks</p>
