If you want to reduce sqrt%2840x%29 then

sqrt%284%2A10x%29 rewrite 40 as the product of 4 and 10

sqrt%284%29%2Asqrt%2810x%29%29 Rewrite the square root of the product as the product of square roots (ie sqrt%28x%2Ay%29=sqrt%28x%29sqrt%28y%29

2%2Asqrt%2810x%29%29 since 4 is a perfect square, it reduces to 2. So this is your reduced form.
