The first step for solving this expression is to simplify the radical in the first set of parenthesis. (6[tex] \sqrt{3} [/tex]) × (3[tex] \sqrt{32} [/tex]) Simplify the radical in the second set of parenthesis. (6[tex] \sqrt{3} [/tex]) × (12[tex] \sqrt{2} [/tex]) Remove the parenthesis off of both sets. 6[tex] \sqrt{3} [/tex] × 12[tex] \sqrt{2} [/tex] Now calculate thee product to find your final answer. 72[tex] \sqrt{6} [/tex] This means that the correct answer to your question is going to be 72[tex] \sqrt{6} [/tex],, or option B.
