Answer 1

$\frac{8*3^{3} }{2*3^{2} } =4*3=12$

$\frac{11^{3}*4^{2} }{11^{2}*4 } = 11*4=44$

$\frac{2^{4}*2^{6}*2^{3} }{2^{5} *2^{7} } =\frac{2^{4+6+3} }{2^{5+7} }=\frac{2^{13} }{2^{12} } =2^{13-12} =2^{1} =2$

$\frac{3^{6}*3^{3} }{3^{5} *3*3} =\frac{3^{6+3} }{3^{5+1+1} } =\frac{3^{9} }{3^{7} } =3^{9-7} =3^{2} =9$

$\frac{(-5)^{9} }{5^{7} } = \frac{(-1)^{9} *5^{9} }{5^{7} } =-1*5^{9-7} =-1*5^{2} =-25$

$\frac{6^{8} }{(-6)^{7} } = \frac{6^{8} }{(-1)^{7}* 6^{7} } = -6^{8-7} =-6$

$\frac{6^{6} }{3^{4} *2^{3} } = \frac{3^{6}*2^{6} }{3^{4} *2^{3} } =3^{6-4}*2^{6-3}=3^{2}*2^{3} = 9*8=72$

$\frac{3^{6}*2^{7}}{6^{5}} = \frac{3^{6}*2^{7}}{3^{5}*2^{5}} = 3^{6-5}*2^{7-5} = 3^{1}*2^{2} = 3*4=12$
