Answer 1

$5) 2^3 : 2^3 = 8 : 8 = 1 \\ \\6) \frac{2 ^{4} \times2 ^{6} }{3 ^{7} \times 3 ^{3} } = \frac{2 ^{10} }{ 3^{10} } = \frac{1024}{59049} \\ \\11) \frac{4 ^{6} \times 8 ^{2} }{16 ^{3} } = \frac{4096 \times 64}{16 ^{3} } = \frac{262144}{4096} = 64 \\ \\ 12) \frac{10 ^{5} \times 10 ^{ - 3} \times 10}{10 ^{ - 7} \times 10 ^{4} } = \frac{10 ^ {3} }{10 ^{ - 7} \times 10 ^{4} } = \frac{10 ^{3} }{10 ^{4 - 7} } = \frac{10 ^{3} }{10 ^{ - 3} } = \frac{10 ^{3} }{ \frac{1}{10 ^{3} } } = \frac{1000}{ \frac{1}{1000} } = 1000 \times 1000 = 10000000$
