Question 300560
 have been trying for days to figure out these problems. i thaught maybe someone could please help me. how do you simplify: 7 times the square root of 3 + the square root of 48

7*sqrt(3) + sqrt(48) =

7*sqrt(3) + sqrt(16*3) =

7*sqrt(3) + (sqrt(16)*sqrt(3)) =

7*sqrt(3) + 4*sqrt(3) =

(7+4)*sqrt(3) =

11*sqrt(3)

Keep trying.  You'll get it :)
