## anonymous 5 years ago what is the derivative of ln(sqrt(x^2)) ? ? Thanks in advance!

1. M

1/x?

2. M

$\ln \sqrt{x ^{2}}$

3. M

is that what you mean?

4. anonymous

ln(sqrt(x^2)) = ln x (d/dx) ln x = 1/x right?

5. M

yes

6. anonymous

$(d / dx) \ln \sqrt{x^{2}}$

so its ok to go ahead and cancel the exponent with the square root and then just do ln (x) ?
