X+1/x=3,x^5+1/x^5=? what is the answer

The answer is 123.

Step-by-step explanation:

Given that-

( ) = 3.....................(i)

To find -

( ) = ?

Now squaring both sides of equation (i)-

( ) = 9

( ) = 7....................(ii)

On cubing equation (i) both sides-

( ) = 27

( ) = 27

( ) = 27 - 9

( ) = 18.....................(iii)

Multiply equation (i)  and equation (ii)-

( )  ( ) = 7 × 18

( = 126

( [tex]x^{5} + \frac{1}{x^{5} } ) = 126 - 3

( [tex]x^{5} + \frac{1}{x^{5} } ) = 123

96 39 cause 135 -96=39 im smart (i used a calculater)

two? xd
