Question

Помогите решить пример​

Answer 1

Ответ:

$\frac{1}{9}$

Пошаговое объяснение:

$\frac{(4*3^{22}+7*3^{21})*57  }{(19*27^{4} )^{2} }=\frac{3^{21}*(12+7)*3*19 }{19^{2}*3^{3*4*2}  }  =\frac{3^{22}*19^{2}  }{19^{2}*3^{24}  } =3^{-2} =\frac{1}{9}$

Answer 2

Ответ:

$\frac{(4 \times {3}^{22} + 7 \times {3}^{21}) \times 57 }{ {(19 \times {27}^{4} })^{2} } = \frac{(12 \times {3}^{21} + 7 \times {3}^{21} )57}{ {(19 \times { 3}^{12}) }^{2} } = \frac{19 \times {3}^{21} \times 57}{ {19}^{2} \times {3}^{24} } = \frac{57}{19 \times {3}^{3} } = \frac{57}{513} = \frac{1}{9}$
