Best ResponseYou've already chosen the best response.0Okay, do it. What's preventing you from doing the two multiplications, one in the numerator and one in the denominator? Never post a problem with no work shown.

Best ResponseYou've already chosen the best response.0I am never rude. I am honest and direct. This is often mistaken for rudeness. I have yet to see an online program that was particularly helpful. They may be out there. I just haven't seen them. You must multiply by whatever will make the denominator rational. \(\dfrac{3}{\sqrt{2}} = \dfrac{3}{\sqrt{2}}\cdot\dfrac{\sqrt{2}}{\sqrt{2}} = \dfrac{3\sqrt{2}}{2}\) See how that works?
