I am having a bit of trouble expressing me answer in the correct simplified form.

The answer is... 2.45/2.5x10^17m^-2 (m is meters)

-what is the correct form to express this answer?

Is this what it looks like?
$$\frac{2.45}{2.5x10^{17} m^{-2}}$$

Do you mean:

$$\frac {2.41} {2.5 x 10^{17}} m^{-2}$$

or

$$\frac {2.41} {2.5 x 10^{17} m^{-2}}$$

What do you know about operations with exponents?

Integral - it is the second one you have described.

-I'm thinking that it would just be 2.45*2.5*10^17m^2 ?

..and then I would solve
