This is an expression which combines the exponents of the same variable by simply adding them:
1/2+2/3=7/6, which is also applied to the constants 2 and 3. That means x^(7/6) has to be multiplied by square root of 2 (approx 1.414) and the cube root of 3 squared, that is, cube root of 9=2.080 approx.
So the answer is 2.942x^(7/6).
