Nothing it is simplified
20
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.
The population of Radical Performance Engines is 20.
The ratical, or square root, of 20 is approximately 4.472135954999579
√400 = 20, -20
the letter i means a complex number. it means square root of -1. whenever you have numbers outside the radical all you have to do is square them to get them inside the radical.so square i and square 2i2 radical 20 is the same are your new form... radical negative 80but your numerical answer is 8.94i
2√5
2√5
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
It would be 20 radical 109, or about 208.8061302
