10-44.

Express $\operatorname{ln}(4.5)$ in terms of $\operatorname{ln}3$ and $\operatorname{ln}2$. Use any of the logarithmic identities listed below.

$\operatorname{ln}(ab) =\operatorname{ln} a +\operatorname{ln} b$

$\operatorname { ln } ( \frac { a } { b } ) = \operatorname { ln } a - \operatorname { ln } b$

$\operatorname{ln}(a^b) = b\operatorname{ln} a$
