(0.2)^-1*5^4*25^4*(0.2)^-4

Answer 1

$0,2^{-1} * 5^{4} * 25^{4} * 0,2^{-4} = ( \frac{2}{10} )^{-1} * 5^{4} * ( 5^{2} )^{4} * ( \frac{2}{10} )^{-4} = \frac{ \frac{1}{ 2^{1} } }{ \frac{1}{ 10^{1} } } * 5^{4} * 5^{8} *$
$* \frac{ \frac{1}{ 2^{4} } }{ \frac{1}{ 10^{4} } } = \frac{1}{2} * \frac{10}{1} * 5^{12} * \frac{1}{ 2^{4} } * \frac{ 10^{4} }{1} = \frac{2*5* 5^{12}*1* 2^{4}* 5^{4} }{2* 2^{4} } = 5^{17}$
