Find the limit.
lim 5x/(x^225)
x>5
Here is the work I have so far:
lim 5x/(x^225) = lim 5x/(x5)(x+5)
x>5 x>5
lim (1/x+5) = lim 1/10
x>5 x>5
I just wanted to double check with someone and see if the answer is supposed to be positive or negative. For the lim The answer I received is
x>5 positive 1/10
Please confirm with me if this answer is correct! Thank you!
