Answer

$\displaystyle \frac{69}{4}=17.25$

Work Step by Step

$\displaystyle \int_1^8\frac{2+t}{t^{2/3}}dt = \int_1^8\frac{2}{t^{2/3}}+\frac{t}{t^{2/3}}dt=\int_1^82t^{-2/3}+t^{1/3}dt$ $\displaystyle (\frac{2t^{1/3}}{1/3}+\frac{t^{4/3}}{4/3})|_1^8$ $\displaystyle (6t^{1/3}+\frac{3}{4}t^{4/3})|_1^8$ $\displaystyle [6(8)^{1/3}+\frac{3}{4}(8)^{4/3}]-[6(1)^{1/3}+\frac{3}{4}(1)^{4/3}]$ $\displaystyle [6(2)+\frac{3}{4}(2)^4]-[6+\frac{3}{4}]$ $\displaystyle 12+\frac{3}{4}(16)]-6-\frac{3}{4}$ $\displaystyle 12-6-\frac{3}{4}+3(4)$ $\displaystyle 6+12-\frac{3}{4}$ $\displaystyle 18-\frac{3}{4}$ $\displaystyle \frac{72}{4}-\frac{3}{4}$ $\displaystyle \frac{69}{4}=17.25$
