Answer:
4√15
Step-by-step explanation:
Factor 240 into its prime factorization. 240 can be factored as 2 x 2 x 2 x 2 x 3 x 5.
Identify any perfect squares that can be factored out. In this case, we can see that 2 x 2 x 2 x 2 = 16, which is a perfect square.
Take the square root of the perfect square and put it outside the radical. So, √240 = √(16 x 15).
Simplify the expression by taking the square root of 15. √240 = 4√15.
The reduced form of √240 is 4√15.
