√(6)√(30) =
√(6)√(5×6) =
√(5×6×6) =
√(6×6)√(5) =
6√(5)
This is because we know for any quantities a and b:
√(a)√(b) = √(ab)
We run that rule both ways to simplify this problem.

â6 * â30 = â180
â(36 * 5) = â180
6â5 = â180
.

x = ( 6 * (30^.5)^.5)
x = ( 6 * 5.4772)^.5
x = (32.8634)^.5
x = 5.7326

= SQRT(180) = SQRT (36 X 5) = (6)(SQRT 5)
