# Natural log fxn = negative integral?

## Homework Statement

True or false?

ln(1/10) = -$$\int$$ dx/x

## The Attempt at a Solution

I have no idea where to start on this one.

what is dx/x ??

right side means that u are supposed to integrate with respect to x

-Integrate[1/x] with respect to x

This is obviously not true as posted. Are there limits of integration that we're not seeing?
I.e., does the integral look like this?
$$-\int_1^{10} \frac{dx}{x}$$

ok I get it. the limits are missing, it must be a typo, but otherwise this makes sense to me now thanks
