20 times the square root of 2
sqrt(12)*sqrt(20) = sqrt(12*20) = sqrt(240) = sqrt(16*15) = sqrt(16)*sqrt(15) = 4*sqrt(15)
Here is an example, radical 20 plus radical 5. Now radical 20 is 2(radical 5) so we can add radical 5 and 2 radical 5 and we have 3 radical 5.
"Radical x times radical x" could be interpreted as the square root of x times the square root of x - in which case the product would be x (the number under the radical sign)

sqrt(12)*sqrt(20) = sqrt(12*20) = sqrt(240) = sqrt(16*15) = sqrt(16)*sqrt(15) = 4*sqrt(15)
√32 * √20 = √(32*20) = √(640) = √(2*2*160) = 2√(160) = 2√(2*2*40) = 4√(40) = 4√(2*2*10) = 8√10
