Question

надо!
a1:=10/(17x)
a2:=a1/x
a3:=a2/x
a4:=a3/x
y:=a1+a4

Answer 1

Объяснение:

$a _{1} = \frac{10}{17x}$

$a _{2} = \frac{a _{1} }{x} = \frac{ \frac{10}{17x} }{x} = \frac{10}{17x} \times \frac{1}{x} = \frac{10}{17x ^{2} }$

$a _{3} = \frac{a _{2} }{x} = \frac{ \frac{10}{17 {x}^{2} } }{x} = \frac{10}{17x ^{2} } \times \frac{1}{x} = \frac{10}{17 ^{3} }$

$a _{4} = \frac{a _{3} }{x} = \frac{ \frac{10}{ {17x}^{3} } }{x} = \frac{10}{ {17x}^{3} } \times \frac{1}{x} = \frac{10}{ {17x}^{4} }$

$y = a _{1} + a _{4} = \frac{10}{17x} + \frac{10}{ {17x}^{4} } = \frac{10010}{ {17x}^{4} }$
