Question 901039
 {{{3log(2,9/8) +4log(2,16/15) - 2log(2,24/15) }}}
=  {{{log(2,(9/8)^3) + log(2,(16/15)^4) - log(2,(8/5)^2) }}}
= {{{log(2,((9^3*16^4/(8^3*15^4)))/((64/25)))}}}
= {{{log(2,((3^6*2^16/(2^9*15^4)))/((2^6/25)))}}}
= {{{log(2,((3^6*2/(3^4*5^4)))/((1/25)))}}}
= {{{log(2,((3^2*2/(5^4)))/((1/25)))}}}
= {{{log(2,((3^2*2/(5^2))))}}}
= {{{log(2,(18/25))}}}
= {{{log(2,0.72)}}}
= log(0.72)/log(2)
