25 pointssimplify the radical expression. show all your steps. -3

Note that 363 = 3(121), and that 121=11^2.  Thus, sqrt(363) = 11sqrt(3).

Also note that the cube root of 27 is 3.

But perhaps you meant 3 times the square root of 27.  In that case, you'd have 3sqrt(3)sqrt(9) = 9 sqrt(3).

I'd go with the following:  11sqrt(3) - 9sqrt(3) = 2 sqrt(3) (answer).

Don’t worry about it
