Question

Evaluate the definite integral

Answer 1

lets see this warlock!

Answer 2

\[\int\limits_{2}^{8} (4/\sqrt(x)) dx \]

Answer 3

\[\int\limits_{2}^{8}\frac{4}{\sqrt{x}}dx=\int\limits_{2}^{8}\frac{4}{x^\frac{1}{2}}dx=\int\limits_{2}^{8}4x^\frac{-1}{2}dx=\frac{4*x^{\frac{-1}{2}+1}}{\frac{-1}{2}+1} ,x=2..8\]

Answer 4

\[\frac{4*x^\frac{1}{2}}{\frac{1}{2}}, x=2..8=2*4x^\frac{1}{2},x=2..8=8x^\frac{1}{2}. x=2..8\]

Answer 5

when I check my answer it gives me 11.3137.

Answer 6

\[=8\sqrt{8}-8\sqrt{2}=8(\sqrt{8}-\sqrt{2})=8(2\sqrt{2}-\sqrt{2})=8(1\sqrt{2})=8\sqrt{2}\]

Answer 7

yes thats right good job
