Question

The integrals in Exercises 1–44 are in no particular order. Evaluate each integral using any algebraic method, trigonometric identity, or substitution you think is appropriate.
∫ (2^(√y) dy) / 2√y

Accepted Answer

Start by examining the integral: $$\int \frac{2$$^{\sqrt{y}$$}}{2\sqrt{y}} \, dy. $$Notice that the expression involves $$\sqrt{y}$$ both in the exponent and the denominator, suggesting a substitution involving $$\sqrt{y}$$ might simplify the integral. Let $$u = \sqrt{y} = y$$^{1/2}$$. Then, differentiate both sides with respect to y$ to find du$ in terms of dy$: u$$ = $$y^{1/2}$$ \implies du = \frac{1}{2\sqrt{y}} dy$$. Rearrange the differential to express dy$ in terms of du$: from du$$ = \frac{1}{2\sqrt{y}} dy$$, multiply both sides by 2$$\sqrt{y}$$ to get dy = 2$$\sqrt{y} \, du$$. Substitute u$ and dy$ back into the integral: replace 2$$^{\sqrt{y}$$}$$ with $$2^u$$ and $$dy$$ with $$2\sqrt{y} \, du. $$Notice that the $$2\sqrt{y} in $$the denominator and numerator will cancel out, simplifying the integral to $$\int 2^u \, du. $$Now, integrate $$\int 2^u \, du$$ using the formula for integrating exponential functions with base $$a$$: $$\int a^u \, du = \frac{a^u}{\ln(a)} + C. $$Apply this formula with $$a=2 to $$find the antiderivative in terms of $$u$$, then substitute back $$u = \sqrt{y} to $$express the answer in terms of $$y.$$
