You can rewrite the limit as $$\lim_{x \rightarrow 1} {{x^{1\over m} - 1 \over x - 1} \over {x^{1 \over n} - 1 \over x- 1}}$$ By the quotient rule for limits this is exactly $${\lim_{x \rightarrow 1} {x^{1 \over m} - 1 \over x - 1} \over \lim_{x \rightarrow 1} {x^{1 \over n} - 1 \over x - 1}}$$ But notice that for any $\alpha$, ${\displaystyle \lim_{x \rightarrow 1} {x^{\alpha} - 1 \over x - 1

mathman said: One way to solve it is by observing that; x 1/x =e lnx/x. Using the Limit Laws, we can write: = ( lim x → 2 − x − 3 x) ⋅ ( lim x → 2 − 1 x − 2). 2. Can a limit be infinite? A limit can be infinite when the value of the function becomes arbitrarily large as the input approaches a particular value, either from above or below. x→1. Notice that as the x x -values get closer to 6, the function values appear to be getting closer to y = 4 y = 4. x → ∞lim 36 x2 + 7 x + 49 − 6 x. Does not exist Does not exist.
Here is another way to solve the Problem, without using . If the function is not continuous, even if it is defined, at a particular point, then the limit will not necessarily be the same value as the actual function.
To understand what limits are, let's look at an example. However, just in case you haven't covered it, remember from your algebra days that.4 Use the epsilon-delta definition to prove the limit laws. We start with the function f ( x) = x + 2 . However, you typically need to know limits before you learn calculus, and you need to know

Figure 2. the answer is m/n but i have no idea how to start or solve this! As Subhotosh Khan indicated, L'Hospital's Rule would make quick work of this problem. It is important to remember, however, that to apply L'Hôpital's rule to a quotient f ( x) g ( x), it is essential that the limit of f ( x) g ( x) be of the form 0 0 or ∞ / ∞. It is how I learned to write them up, and
lim x!a f(x) = 1 or lim x!a+ f(x) = 1 or lim x!a f(x) = 1 or lim x!a+ f(x) = 1: Again: If any one of these holds, then x= ais a vertical asymptote. BUT we can do this: limx→∞ x+cos(x)x = limx→∞ (1 + cos(x)x) As x goes to infinity then cos(x)x tends to between −1∞ and +1∞, and both tend to zero. As ln(x 2) − ln(x 1) = ln(x 2 /x1).
When x=1 we don't know the answer (it is indeterminate) But we can see that it is going to be 2; We want to give the answer "2" but can't, so instead mathematicians say exactly what is going on by using the special word "limit" The limit of (x 2 −1) (x−1) as x approaches 1 is 2. And because it just wiggles up and down it never approaches any value. In this section we relax that definition a bit by considering situations when it makes sense to let c c and/or L L be "infinity.

The limit of a function is a fundamental concept in calculus. Evaluate the limit of by
lim x->0 1/x. Since x − 2 is the only part of the denominator that is zero when 2 is substituted, we then separate 1 / (x − 2) from the rest of the function: = lim x → 2 − x − 3 x ⋅ 1 x − 2. Factoring and canceling is a good strategy: lim x → 3 x2 − 3x 2x2 − 5x − 3 = lim x → 3 x(x − 3) (x − 3)(2x + 1) Step 2. Suppose lim x → ag(x)ln(f(x)) = L, where L may be ∞ or − ∞.

Analysing the limit we have $0^0$ on the numerator (which would require using logs) but also $- \infty$ on the denominator. Graphically, this is the y -value we approach when we look at the graph of f and get closer and closer to the point on the graph where x = 3 . limx → ∞ ( 2x3 − 2x2 + x − 3 x3 + 2x2 − x + 1 ) Go!

Calculus.
Therefore, lim x → ag(x)ln(f(x)) is of the indeterminate form 0 ⋅ ∞, and we can use the techniques discussed earlier to rewrite the expression g(x)ln(f(x)) in a form so that we can apply L'Hôpital's rule. Notice that $$\frac{d}{dx} \sin x := \lim_{h \to 0} \frac{\sin(x+h)-\sin x}{h} \equiv \lim_{h \to 0} \left[ \left(\frac{\cos h -1}{h}\right) \sin x+ \left(\frac{\sin h}{h}\right) \cos x \right].
