Answer 1

OK , I assume that everything the the right of the / sign is under the sq root, would help to put ( ) around what is under the root sign.  I also assume you want to know the simplified version

8) this is the same as sqrt(16) * sqrt (x^10) = 4*x^5

9) sqrt(6) * sqrt (9) * sqrt (x^11) = 3*sqrt(6)*x^5.5

the rest are done the same way, just repeat
