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
That is the simplest radical form of the actual fraction, 7/4 ===
4 x2
The square root of 28 or in this case the radical form of 28 will be 2 times radical 7. Since 28 is 4 times 7 and the square root of 4 is two.

12 times the square root of 7.
It is -sqrt(7).
4 times radical 34
4√3 + 7√3 = (4 + 7)(√3) = 11√3
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
That is the simplest radical form of the actual fraction, 7/4 ===
4 x2
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)
First, note that radical 4 is 2. So 3xradical 4 is just 6, Now we have 6+2 radical 3. You can't do much with this except factor out a 2 if you want 2(3+Radical 3)
