Root(75x^3)=Root(25)Root(3)Root(x^2)Root(x)=5xroot(3x)
xroot(27x)=xroot(9)root(3)root(x)=3xroot(3x)
so 5xroot(3x)-3xroot(3x)=2xroot(3x)
so basically start by factoring stuff so that it looks alike
so 75 and 27 have a common factor of 3 so
root (25*3* x^3) -xroot (9*3x)
so you can then pull out squares. root 25=5 and root 9=3 so
5xroot(3x)-3xroot(3x)
Then combine them cause they're like terms now
2xroot(3x)
5x sqrt 3x - 3x sqrt 3x =
2x sqrt 3x
Its over 9000!!!!
