semenoff76 1) $\frac{27*8*72}{32*162*69} = \frac{9*36}{23*4*81} = \frac{1}{23}$

2) $( \frac{5}{8} + \frac{7}{12} )*(3 \frac{23}{58} -2 \frac{9}{58} )= \frac{15+14}{24}*1 \frac{14}{58} = \frac{29}{24} * \frac{36}{29} = \frac{36}{24}$ $=1.5$

$a^{4}- b^{4} + b^{2} -a^{2} =(a^{2}-b^{2})( a^{2} + b^{2} )-(a^{2} - b^{2} )= \\ =(a^{2} - b^{2} )( a^{2} + b^{2} -1)=(a{} - b{} )(a+b)( a^{2} + b^{2} -1)$
