How would I simplify this?
Here is the equation:
4sqrt75 * sqrt27
Would i just add 75 and 27 or is there something that I am missing?

You can't add or subtract sqrts unless your square-rooting the same numbers (ex. sqrt3+sqrt3)
take 75/5= 15 then 15/5=3... because there are two fives you can remove them from under the square root and multiply 4 by 5 so you have 20sqrt3. now take 27/3=9 now take 9/3=3 take the 3's out you get 3sqrt3. now multiply 3sqrt3 by 20sqrt 3 which equals 180. or if your adding it would be 23sqrt3. subtracting would be 17sqrt3.
