пожалуйста помогите срочно !!!!​

Answer 1

$\frac{ {x}^{5} \times {( {x}^{4} \times x ) }^{3} }{ {( {x}^{2} )}^{9} } = \frac{ {x}^{5 + 12 + 3} }{ {x}^{18} } = \frac{ {x}^{20} }{ {x}^{18} } = {x}^{20 - 18} = {x}^{2} \\ \\ {x}^{2} = { (\frac{1}{7} )}^{2} = \frac{1}{7} \times \frac{1}{7} = \frac{1}{49} \\ {x}^{2} = {(0.7)}^{2} = 0.7 \times 0.7= 0 . 49$
