(12 points) Note: You can get full credit for this problem by just answering the last question correctly. The initial questions are meant as hints towards the final answer and also allow you the opportunity to get partial credit. Also the appropriate way to enter roots (except sqrt) into WeBWork is to use fractional exponents.\ Consider the definite integral $\int_0^1 \frac{dx}{\sqrt{x} + 7\sqrt[7]{x}}$ Then the most appropriate substitution to simplify this integral is $u = x^(1/2)$ Then $dx = f(x) du$ where $f(x) = $ After making the substitution and simplifying we obtain the integral $\int_a^b g(u) du$ where $g(u) = $ $a = $ $b = $ This definite integral has value =
