Can anyone help me in my problem again? Here's my problem in limits:
Lim ((Square root of 7 + a) - square root of 7) over a
a->0
Hope you can help me. Thanks in advance. :)

Finally. A problem besides "solve x+1=0 for x".:)
Multiply the top and bottom by the conjugate of the numerator.
This gives:
Now, can you see what you get as a-->0? Tell me what you get.
I end up with an answer:
1/square root of 14
Is my answer correct? Because the hand out that was given to us tells that the answer is (square root of 7)/14.
How did they get that answer? There is no solution given in my hand out, that's why I'm trying to solve this one on my own and with your help. :)
How did you get that? Just bu plugging in a=0 in the limit, we get
The solution should be
Oh.. Stupid me. :D now I know my mistake. When I add square root of 7.. The answer that I got was square root of 14.
I forgot that there is invisible 1 before square root of 7. What I did was I just simply add the 2 values inside the square root sign.
I will always remember that scenario whenever I will encounter square r0ots..
thank you very much for your help! More powers to you! :)
