Hi! So to solve for these, all you have to do is keep PEDMAS in mind. For example, for 2x^3 (Just a fancy way of writing "to the third power") first plug in 3: 2(3)^3 and take it to the third power because E (exponent) comes before M (multiplication) in PEDMAS. You should get 2(27) which then equals 54. Hope this helps:)
