Hi, I am having problem with one difficult looking logarithm. Please help me!

$\displaystyle

3log_2 \frac{9}{8} + 4*log_2 \frac{16}{15} - 2 log_2 \frac{24}{25}

$

Thanks! Please show your working -

*EDIT: This is supposed to be solved without an calculator, so can you please simplify it down to something which you can easily work with, with logarithm laws.

Thanks
