The square root (radical) of 5 is about 2.2361 (an irrational number)
sqrt(162) = sqrt(81*2) = sqrt(81)*sqrt(2) = 9*sqrt(2)
sqrt(162) = sqrt(81*2) = sqrt(81)*sqrt(2) = 9*sqrt(2).
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.
sqrt(25/81) = +/- 5/9
5sqrt(405) = 5sqrt(815) = 5sqrt(81)sqrt(5) = 59sqrt(5) = 45sqrt(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 times radical 5 or about 4.472135955
Not necessarily. If it is the same radical number, then the signs cancel out. Radical 5 times radical 5 equals 5. But if they are different, then you multiply the numbers and leave them under the radical sign. Example: radical 5 * radical 6 = radical 30
Sqrt[5*radical(68)] = -6.4211 and +6.4211.

Sqrt(162) = sqrt(81*2) = sqrt(81)*sqrt(2) = 9*sqrt(2)
4√5 + 4√5 = 8√5.
5% of 81kg= 5% * 81= 0.05 * 81= 4.05kg
