How would one go about evaluating the limit of pic related?
>>54802
The exponents are the same so the solution should be -sqrt(x)/sqrt(x) = -1
>>54804
But the 6's cannot cancel, correct? So what happens to the 6's?
>>54808
As x tends towards infinity, sqrt(x) gets very, VERY large. Infinitely large, in fact. Adding a constant (like 6) to an infinitely large number really makes no difference in the result, so in the case of this limit, the 6s can be ignored.
