√3 x √21 = √3 x √(3 x 7) = (√3 x √3) x √7) = 3√7

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

3 divided by 7 is:3/7 = 0.428571428 calculating to 9 decimal places.
Radical 147 simplified is 7 radical 3. radical147= radical 49* radical 3 the square root of 49 is 7 therefore the answer is 7 radical 3
13.8564
7/3= 7 ÷ 3= 2.333 in decimal
7 3/8 as a decimal is : 7.375
In radical form, 3* sqrt(41). The decimal approximation is 19.20937271.
Expressed as a decimal, 7 3/5 is equal to 7.6.
3/7 = 0.428571 repeating

The concept of a factor makes proper sense only in the context of integers. Otherwise, any non-zero number can be factor of any other number. For example, radical 7 is a factor of radical 18 since radical(180) = radical(7) * radical (18/7)
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.

-3*radical(2)*radical(50) = -3*radical(2*50) = -3*radical(100) = -3*10 = -30
