помогите !!!!!!!!!!!!

Answer 1

$\frac{ 20^{47} }{ 5^{48} * 2^{93} } = \frac{ (2*2*5)^{47} }{5^{48} * 2^{93}} = \frac{ 2^{47}* 2^{47}* 5^{47}}{5^{48} * 2^{93}} = \frac{ 2^{47+47}* 5^{47} }{5^{48} * 2^{93}} = \frac{ 2^{94}* 5^{47} }{5^{48} * 2^{93}} = 2^{1 } * 5^{-1} =$ 2 * 1/5 = 2/5 = 0,4
Ответ: 0,4
