The Attempt at a Solution
Mod note: The integral is ##\int x^3 \sqrt{x^2 + 16} dx##
The published answer is ##1/5(x^2+16)^{5/2} -16/3(x^2+16)^{1/2}+C##
To the OP: Using $ $ (i.e., with a space between the $ symbols) causes the browser to not render what's between the $ pairs. For inline LaTeX, you can use # # (no space) at the beginning and end.
