Question

Simplifying radicals help needed

Answer 1

\[\sqrt{12} * \sqrt{27}\]

My work:

\[\sqrt{12} * \sqrt{27}\]
\[=\sqrt{2} * \sqrt{6} * \sqrt{3} *\sqrt{9}\]
-----------------------------------------
Besides simplifying sqrt9 to 3, I don't know what else am supposed to do.

Answer 2

Why not multiply the rest together to get sqrt(36)? Would that work? Been a while since I've done this

Answer 3

I manually calculated it in a calc, and that seems to be a valid step

Answer 4

So \[\large \sf \sqrt{2} \times \sqrt{6} \times \sqrt{3} = \sqrt{36} = 6\] \[\large \sf 6 \times 3 =18\]

Answer 5

That make sense to ya?
