√2x^3/3x
I suppose this means \[\frac{ \sqrt{2x^3} }{ 3x }\]
So you can split up the terms in the equation like this\[\frac{ \sqrt{2xx^2} }{ 3x }\]
So how can you simplify the square root?
Well can you take some stuff out of the square root?
You're close, there's a reason I made it x^2 Can't you take that out?
Yeah so how can you write that when you take out the x^2?
Well no,... Let's use an example, what is\[\sqrt{2^2}?\]
Yup that's right \[\sqrt{2^2}=2\] So following that pattern couldn't we say that \[\sqrt{x^2}=x?\]
So another way to write\[\frac{ \sqrt{2x}\times \sqrt{x^2} }{ 3x }\]
Using what I said earlier\[\sqrt{x^2}=x\] So this becomes\[\frac{ \sqrt{2x}\times x }{ 3x }\]
So the x cancels out in the denominator and the numerator and this becomes\[\frac{ \sqrt{2x} }{ 3 }\]
Which is the simplest you can get it to
