Пожалуйста срочно заранее спасибо

Answer 1

76.
1)
$frac{a {}^{8} times a {}^{5} }{a {}^{3} times a {}^{6}} = frac{a {}^{13} }{a {}^{9} } = a {}^{4}$
2)
$frac{a {}^{9} times a {}^{6} }{a {}^{5} times a {}^{8} } = frac{a {}^{15} }{a {}^{13} } = a {}^{2}$
3)
$frac{(a {}^{8}) {}^{4} times (a {}^{4}) {}^{3} }{a {}^{6} times a {}^{9} } = frac{a {}^{32} times a {}^{12} }{a {}^{15} } = frac{a {}^{44} }{a {}^{15} } = a {}^{29}$
4)
$frac{a {}^{6} times (a {}^{3}) {}^{4}}{(a {}^{4}) {}^{3} times a {}^{2} } = frac{a {}^{6} times a {}^{12} }{a {}^{12} times a {}^{2}} = frac{a {}^{18} }{a {}^{14} } = a {}^{4}$
