# Thread: l'Hopital's Rule

1. can anyone help me solve this question?

where is a non-zero constant different from

thank you

2.

3. oo and one more question,

a regular polygon has an interior angle that is 8 times bigger than its exterior angle. how many sides does this polygon have?

thank you

4. Answer to 1)

I am not sure if i did this right but i applied l'hopitals rule about 4 times and obtained
-2 as a final answer.

This one is quite simple if you apply the rules of polygons.

sum of exterior angles = 360 degrees

sum of interior angles of an n-sided regular polygon = (n-2)*180

think it gives 18 but may have got that wrong too

5. yes, it is in fact -2, i tried it also and got the same answer, and same goes for the other angle one, got 18 sides too.

anyway thank you for the confirmation of the answer.
