carolyn.dix: im having a lot of trouble of multiplying radicals
Hi Carolyn
sqrt3 * root3 = sqrt(3*3) = sqrt9 = 3
2sqrt6 * 7sqrt12 = 2 * 7 * sqrt6 * sqrt12 = 14 * sqrt72
but sqrt72 = sqrt(36*2) = sqrt36 * sqrt2 = 6sqrt3
so
14*sqrt72 = 14 * 6 * sqrt3 = 84sqrt3
Does that help at all.
Here's a you tube clip. It is very good!
