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
12 radical 2 you multiply 6 and 2 :)
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
