I don't know if this is right.
directions: Simplify each radical expression.

(radical 3+5)(radical 3-3)

i think its:

radical 3+2

Life would be so much simpler if you would use parenthesis. Did you mean this?

(sqrt3 + 5)(sqrt3 -3) ?

multiply that out
sqrt3*sqrt3 -3sqrt3 +5sqrt3 -15
now combine and simplify terms.
