It depends. Is the entire expression squared or just radical 7?Assuming the latter, then 6 + (√7)^2 = 6 + 7 = 13.
6√5 + 2√5 - 7 = 8√5 - 7, which cannot be simplified.

It is -sqrt(7).
7*sqrt(600) = 7*sqrt(100*6) = 7*sqrt(100)*sqrt(6) = 7*10*sqrt(6) = 70*sqrt(6)
It depends. Is the entire expression squared or just radical 7?Assuming the latter, then 6 + (√7)^2 = 6 + 7 = 13.
294 is an integer and there is no sensible radical form for it.
6√5 + 2√5 - 7 = 8√5 - 7, which cannot be simplified.
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.
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)
