Answer 1

Answer:

Step-by-step explanation:

Answer 2

$HEYA \: \\ \\ x= 1 + y + y {}^{2} + y {}^{3} + ... + \infty \\ \\ the \: above \: series \: form \: a \: g.p \: becoz \\ \: common \: ratio \: is \: \: same \: and \: its \\ \: sum \: is \: is \: given \: by \: \: a \div (1 - r) \\ where \: a \: is \: ist \: term \: and \: r \: is \: common \: ratio \\ \\ here \: a \: = 1 \: and \: r \: =y \\ \\ x = 1 \div (1 - y) \\ \\ x(1 - y) = 1 \\ \\ x - xy = 1 \\ \\ (x - 1) = yx \\ \\ y = (x - 1) \div x$
