To evaluate the limit (2^x+sinx)/x^4 as x approaches 0, we can use L'Hôpital's Rule. Taking the derivative of the numerator and denominator separately, we get (ln(2)*2^x+cosx)/4x^3. Substituting x=0 into this expression, we find the limit is ln(2)/0, which is undefined.

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.
