a)
[tex]\frac{2^{4} *3^{3}*8^{5} }{16^{4}*3} =\frac{2^{4} *3^{3}*(2^{3})^{5} }{(2^{4})^{4}*3 } =\\\\=\frac{2^{4+15}*3^{3} }{2^{4*4} *3} =\frac{2^{19}*3^{3} }{2^{16}*3 } =\\\\=2^{19-16} *3^{3-1} =2^{3} *3^{2} =8*9=72[/tex]
b)
[tex]\frac{3*64^{2}*11 }{6*16^{3} } =\frac{3*(2^{6})^{2}*11 )}{3*2*(2^{^{4})^{3} } } =\\\\=\frac{3*11*2^{12} }{3*2^{13} } =11*2^{12-13} =11*2^{-1} =\\\\11*\frac{1}{2} =5\frac{1}{2}[/tex]
c)
[tex]\frac{5^{3}*(2^{4} )^{2}}{25*8^{2}}=\frac{5^{3}*2^{8} }{5^{2}*(2^{3})^{2} } =\frac{5^{3}*2^{8}}{5^{2}*2^{6}} =5*2^{2} =20[/tex]
