Answer
48
Work Step by Step
Multiplying the coefficients by each other and the radicals by each other, we obtain:
$(3\sqrt 8)(4\sqrt 2)$
=$(3\sqrt 8)\times(4\sqrt 2)$
=$3(4)\times(\sqrt 2\times\sqrt 8)$
=$12\times(\sqrt {2\times8})$
=$12\times(\sqrt {16})$
=$12\times(\sqrt {4^{2}})$
=$12\times4$
=$48$
