(3√8)(4√3)

1st you multiply the digits that are out of the radicand (√):

(3x4)(√8)(√3) ==> 12(√8)(√3)


2nd you multiply the radicand together (part under the square root):
√8 x √3 =√(8x3) = √24

3rd you multiply by 12 ==> 12√24
But you can simplify: if you notice that 24 = 2³ x 3
12√(2³ x3)==> 12x2√(2x3) ==> final answer 24√3

3*4=12

(square root of 8)(square root of 3)= square root of 24= 2(square root of 6)

12*2(square root of 6)= 24(square root of 6)

The answer is A.
