Problem

√(,80)

Solution

1. Identify the number inside the radical and look for its largest perfect square factor.

2. Factor the number 80 into a product of a perfect square and another integer.

√(,80)=√(,16⋅5)

3. Apply the product property of radicals, which states √(,a⋅b)=√(,a)⋅√(,b)

√(,16⋅5)=√(,16)⋅√(,5)

4. Simplify the square root of the perfect square.

√(,16)=4

5. Combine the results to find the simplified radical form.
