Answer 1

$1)c ^{9} *c ^{2} =c ^{9-2} =c ^{7} \ 2)b ^{8} :b ^{4} =b ^{8-4} =b ^{4} \3) (a ^{5} ) ^{3} =a ^{5*3} =a ^{15} \ 4)(xy) ^{n} = x^{n} y^{n}$
$5)( frac{b}{c} ) ^{3} = frac{b ^{3} }{c^{3} }$

$6) x^{3} * (x^{4} ) ^{3} = x^{3} * x^{12} = x^{15} \ 7) frac{a*a ^{5} }{a ^{7} } = frac{1}{a} \ 8)(-3a ^{3} b ^{5} ) ^{2} =9a ^{6} b ^{10}$

$9) frac{9 x^{3} y^{4} }{15 x^{6} y} = frac{3 y^{3} }{5 x^{3} }$

$10)1*2*3*4=2*12=24 \ 11) frac{c ^{k+5}*c ^{k} }{(c ^{2}) ^{k} } =c ^{k+5+k-2k} =c ^{5}$

$12)10 ^{2(n-1)} =10000 \10 ^{2(n-1)} =10 ^{4} \ 2n-2=4 \ 2n=4+2 \ 2n=6 \ n=3$

$13)55 ^{8} ?11 ^{16} \ 11 ^{8} *5 ^{8} ? 11^{8} *11 ^{8} \ 11 ^{8} *5 ^{8} textless 11^{8} *11 ^{8}$
