lim(x-->1/0) [(x^2+5x+3)/(x^2+x+2)]^x is equal to

1.) e^4
2.) e^2
3.) e^3
4.) e

please give your answer with correct explanations...

This is what you asked:



What does x -->1/0 mean? It's pretty easy to show that the value of this for x =0 is 1, and the value for x = 1 is 2.25, so I suspect you meant to write something else.

1/0 means infinite

Now please give your answer with explanation

I'll let you figure the full explanation, but here's a hint:

If you divide (x^2 + 5x + 3) by (x^2 + x + 2) you get:



What does this become for large values of x?

Now recall that



Can you take it from here?

Sir I had already up to yhis point but after that I am not able to attempt anything

Consider what happens to


as x gets very large. The term goes to infinity much faster than , and goes to zero.

Therefore approaches for large values of .

So now you have



The rest is straight forward, using the formula for that I gave you earlier.

That's why we are asking you to post your attempts so far. It might be difficult to type (but I don't see how more difficult that can be to post the question itself), but in the end, you're saving time for yourself and for us, to avoid the steps you already went through.

Thanks a lot for your answer
