2 times radical 5 or about 4.472135955
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.
2 radical 30
-2 √5 + 3 √5 = (-2 + 3) √5 = 1 √5 = √5
3√250 = 15√10 The cube root of 250 is 5 times the cube root of 2.
2 times radical 5 or about 4.472135955
5 times 3 times 2 times 2. Or 2 radical 15.
radical 30
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.

1 over 2 times radical 6
6 radical 2
5 radical 2 (5√2)
2 radical 30
√2 x √2 = (√2)2 = 2
-2 √5 + 3 √5 = (-2 + 3) √5 = 1 √5 = √5
If we factor 60, we get 60 = 2 * 2 * 3 * 5 So sqrt ( 60 ) = sqrt (2 * 2 * 3 * 5) = sqrt (2 * 2) * sqrt (3 * 5) = 4 * sqrt( 15 ) ____________________________________________________________ actually if you do by just using the simpler way you should get 2 radical 15 since , 60 has the closest perfect square of 4 and non perfect of 15 this is how you should solve radical 60 = radical 4 times radical 15 radical 60 = simplify the 4 to 2 and leave radical 15 So , radical 60 = 2 radical 15 not what is above .
