Question

simplify ( 1 upon 1 + y raise to power minus n) plus (one upon 1 + y raise to power n)​

Answer 1

Your Question:

$( \frac{1}{1} + {y }^{ - n} ) + ( \frac{1}{1} + {y}^{n} )$

Answer:

$(1 + {y}^{ - n} ) + (1 + {y}^{n} )$

$(1 + {y}^{ - n} + 1 + {y}^{n} )$

$(2 + ( \frac{1}{ {y}^{n} } + {y}^{n} ))$

$(2 {y}^{n} + 1 + { {y}^{n} }^{2} ) \div {y}^{n}$

$\frac{1}{ {y}^{n} } ( {y}^{2n} + 2 {y}^{n} + 1)$

Hope this answer helps you ^_^ !
