Question

evaluate int frac{dx}{4x sqrt{x ^{2}}-4^{2}}

Answer 1

\[evaluate \int\limits \frac{dx}{4x \sqrt{x ^{2}}-4^{2}}\]

Answer 2

isnt the square rootof x^2 just x

\[\int\frac{dx}{4x^2 - 4^2}\]
rewrite
\[\int \frac{dx}{(2x)^2 - 4^2}\]
does that look familiar?

Answer 3

i think its
\[\int\limits \frac{dx}{4x \sqrt{x^2-16}} \]
