To find the limit of (2+x)^(1/x) as x approaches 0^-, we can use the concept of exponential limits.

First, we rewrite the expression as e^(ln(2+x) / x).

Next, we take the limit of the exponent as x approaches 0^-.

Using the limit properties, we have ln(2+x) / x = ln(2+x) / (x - 0) = ln(2+x) / x.

Now, we can evaluate the limit of ln(2+x) / x as x approaches 0^-.

By applying L'Hôpital's rule, we differentiate the numerator and denominator with respect to x.

The derivative of ln(2+x) is 1 / (2+x), and the derivative of x is 1.

Taking the limit again, we have 1 / (2+0) = 1/2.

Therefore, the limit of (2+x)^(1/x) as x approaches 0^- is e^(1/2).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
