Question

square route of (x-8) + square route of (3x-288)

Answer 1

Use sqrt(**) for square root
you cant add this coz the value inside the sqrt brackets isn't the same
so i think you wrote it wrong
it may be
sqrt(x-8) + sqrt(36x-288)
then take 36 common factor
sqrt(x-8) + sqrt(36{x-8})
then take 36 out of the square root
sqrt(x-8) + 6 {sqrt(x-8)}
then now you can add them coz the value (x-8) inside brackets of square root is the same
the answer is
7 sqrt(x-8)

Answer 2

Please use sqrt( xxxx ) to indicate square root. Save time-improve clarity. Make us happy. :-)
No straightforward answer to this, you can only add these when the sqrt arguement is the same in both terms.
