i think the answer is 12.67, if not then im not sure. the way i did it was replace all the x’s with 2 so youre left with:
2^3 + 2/3 + 2^3
so, from there you do the exponents 2*2*2 = 8 and 2*2 = 4
after that you do the division of 2/3 and youre left with the decimal 0.67
last step you add it all up to 12.67
hope it helps
