The answer is x = one-eighth.
Try it: 6x = six-eighths = 0.75 That's the right hand side.
On the left:
3 times (x to power of 2/3) = 3 times (cube-root of x-squared)
[that's what index of 2/3 means]
which is 3 times cube-root of (1/8)-squared
which is 3 times cube-root of (1/64)
which is 3 times 1/4
which equals 3/4 = 0.75
Therefore left hand side = right hand side when x = 1/8
There is an algebraic way to get to this solution. Are you interested?

should be to the power of 1/3.
I can't remember my AS/GCSE maths.

Not sure but I'd say 36x cubed
