Did u mean Sqrt(9) * Sqrt(4)?
If yes,
= 3 * 2
= 6

If no, then did u mean [9*Sqrt(2)] * [4*Sqrt(2)]?
If yes,
= 9 * Sqrt(2) * 4 * Sqrt(2)
= 9 * 4 * Sqrt(2) * Sqrt(2)
= 36 * Sq[Sqrt(2)]
= 36 * Sq[2^(1/2)]
= 36 * [2^(0.5)]^2
= 36 * [2^(0.5*2)]
= 36 * (2^1)
= 36 * 2
= 72

36 times plain 2 = 72.

9 (2)^(1/2) * 4 (2)^(1/2)
= 36 (2)^ (2/2)
= 72
