2√20 - 3√7 - 2√5 + 4√63 = 2√(4 x 5) - 3√7 - 2√5 + 4√(9 x 7) = 4√5 - 2√5 - 3√7 + 12√7 = 2√5 + 9√7
5 - 2*sqrt(3) is already in simplest radical form, note that if you said 5 - sqrt(12) is definitely simplified to 5 - 2*sqrt(3).

If the product of two irrationals is a rational, then they are both the same radical of a non-perfect square. For example, radical 5 times radical 5 is 5, since that is by definiton what a radical is.
6 radical 2
2 radical 30
-2 √5 + 3 √5 = (-2 + 3) √5 = 1 √5 = √5
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√20 - 3√7 - 2√5 + 4√63 = 2√(4 x 5) - 3√7 - 2√5 + 4√(9 x 7) = 4√5 - 2√5 - 3√7 + 12√7 = 2√5 + 9√7
2 3/5 = 13/5 as a radical: √132/52 = √169/25 because √169/25 = √169/√25 = 13/5 = 2 3/5
5 radical 3 is just a number.So, asking this is the same as asking 'What are some equivalents to 3?' One could answer 2 * 3 / 2. But this reduces to 3.The situation is the same for your question. One could offer some multiple of 5 radical 3 as an answer but, being a multiple, it would reduce to 5 radical 3.radical 3 is approximately 1.732 but not exactly 1.732 so one cannot say, for instance, that 5 radical 3 = 5 (1.732) = 8.660. In fact, there is not way of expressing radical 3 with a finite number of decimal places. So no-one can write radical 3 = 1.732.... exactly.5 radical 3 is the best one can do.
Well, darling, radical 5 plus 2 radical 5 is simply 3 radical 5. It's like adding apples to apples, just with more math and less fruit. So, go ahead and flaunt that math prowess like a boss!

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 .
Answer: No Explanation: Product of 2/3 and 5 = (2/3)×(5) = (2×5)/3 = 10/3 = 3.333..... So, 3.3333...... is less than 5. Hence, Product of 2/3 and 5 is less than 5.
2 times radical 5 or about 4.472135955
