$1 > 2$ !

Level pending

$\frac {1}{10} > \frac {1}{100}$
$ln \frac {1}{10} > ln \frac {1}{100}$
$ln \frac {1}{10} > ln (\frac {1}{10})^2$
$ln \frac {1}{10} > 2 \cdot ln (\frac {1}{10})$

Cancelling $ln(\frac {1}{10})$ , we obtain $1 > 2$

What option explains the mistake?

1>21 > 21>2 !

$1 > 2$ !
