Simplify the equation
√363 becomes 11 √3
3 √27 becomes 9 √3
11 √3 - 9 √3 = 2 √3
Explanation: Find the factors of each number
363 factors are 33, and 11
Find which one you can take the square root from which is 33 and that is how you get 11 √3
3 √27 can be simplified more because the factors of 27 are 9, 3 take the square root of 9. And multiply the leftover 3 with the outside number which is also 3. Then you get 9 √3
Now just subtract
11 √3 - 9 √3
= 2 √3
Sorry if this is confusing but I hope it helps !!
