To differentiate ( y = x^{8x} ), you would use logarithmic differentiation. First, take the natural logarithm of both sides: ( \ln y = \ln(x^{8x}) ). Then apply the properties of logarithms to simplify: ( \ln y = 8x \ln x ). Differentiate both sides with respect to ( x ): ( \frac{1}{y} \frac{dy}{dx} = 8 \ln x + 8 ). Solve for ( \frac{dy}{dx} ): ( \frac{dy}{dx} = y(8 \ln x + 8) ). Substitute ( y = x^{8x} ): ( \frac{dy}{dx} = x^{8x}(8 \ln x + 8) ).

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.
