Question

Me ajudemmmm,rapidão

Answer 1

$\int\limits^2_1 {\frac{2+x^2}{\sqrt{x}}} \, dx= \int\limits^2_1 \left({\frac{2}{\sqrt{x}}}+\frac{x^2}{\sqrt{x}}\right) \, dx\\\\\int\limits^2_1 \left(2x^{-\frac{1}{2}}+x^{2-\frac{1}{2}}\right) \, dx\\\\\int\limits^2_1 \left(2x^{-\frac{1}{2}}+x^{\frac{3}{2}}\right) \, dx\\\\\left(\frac{2x^{\frac{1}{2}}}{\frac{1}{2}}+\frac{x^{\frac{5}{2}}}{\frac{5}{2}}\right|^2_1\\\\\left( 3.52 \right)$
