Answer 1

Ответ:

$1) \frac{8b {}^{12} }{a {}^{6} }$

$2) \frac{3 {}^{15}a {}^{12} }{15625b {}^{3} }$

$3) \frac{4096a {}^{9} }{5 {}^{27} }$

$4) \frac{6 {}^{9}a {}^{20} }{7 {}^{12}b {}^{18} }$

Объяснение:

$1) \frac{4 {}^{9} \times b {}^{12} }{2 {}^{15} \times a {}^{6} } = \frac{2 {}^{18} b {}^{12} }{2 {}^{15} a {}^{6} } = \frac{2 {}^{3}b {}^{12} }{a {}^{6} } = \frac{8b {}^{12} }{a {}^{6} }$

$2) \frac{3 {}^{15} \times a {}^{12} }{5 {}^{6} \times b {}^{3} } = \frac{3 {}^{15}a {}^{12} }{15625b {}^{3} }$

$3) \frac{( {4}^{3} ) {}^{2} \times a {}^{9} }{5 {}^{12} \times (5 {}^{5}) {}^{3} } = \frac{4 {}^{6} a {}^{9} }{5 {}^{12} \times 5 {}^{15} } = \frac{4096a {}^{9} }{5 {}^{27} }$

$4) \frac{6 {}^{9} \times (a {}^{3}) {}^{4} }{(7 {}^{4} ) {}^{3} \times b {}^{18} } = \frac{6 {}^{9}a {}^{20} }{7 {}^{12}b {}^{18} }$
