1/x + 1/x^2 + 1/x^3

Well, you'll have to simplify that, so the first step is the LCD. The LCD of those 3 would be x^3. If we rewrite all 3 with the new denominator, we have
(x^2 + x + 1)/x^3
I guess that's just about it.

1/x + 1/x^2 + 1/x^3
okay, the common denominator is x^3:
(x^3)/x + (x^3)/x^2 + (x^3)/(x^3) =
x^2 + x +1
can you take it from here?

Try posting the whole question. We cant tell what you need help with. What are you supposed to do? Find the value of x? If so, you have to tell us what the summation is equal to. combine them all into one fraction? you have to tell us more info.

I will explain the method. U can solve it. The LCM is X. (Least common multiple.).
Use that method to get the answer.
