6x³+8x

First, replace all the x's with 5's since we're trying to find the value of this expression when x = 5.

6(5)³ + 8(5)

Solve for 5³, which is 5*5*5 = 125.

6(125)+8(5)

Do all the multiplication before addition (order of operations)

750 + 40

Now, add

790

That's your answer. Let me know if you need any clarifications.

Happy Studying~
