a1:=10/(19x)a2:=a1/xa3:=a2/xa4:=a3/xy:=a1+a4
решите плиз

Answer 1

$displaystyle a_1= frac{10}{19x}; quad a_2= frac{a_1}{x}= frac{10}{19x^2}; quad a_3= frac{a_2}{x}= frac{10}{19x_3}; \ \ a_4= frac{a_3}{x}= frac{10}{19x^4}; quad y=a_1+a_4=frac{10}{19x}+ frac{10}{19x^4}= frac{10}{19x}left (1+ frac{1}{x_3}right)$
