sqrt%2824%29=sqrt%284%2A6%29 Factor 24 into 4*6 (notice how 4 is a perfect square)

sqrt%2824%29=sqrt%284%29%2Asqrt%286%29 Break up the root

sqrt%2824%29=2%2Asqrt%286%29 Take the square root of 4 to get 2

So sqrt%2824%29 simplifies to 2%2Asqrt%286%29

Use a calculator to get this approximation sqrt%2824%29=4.898979 and then round 4.898979 to two decimal places to get 4.90
