Hi ,
here is your answer !!!
given , = 1 -√2
we have to find value of ( x -1/x ) ³.
1/ x =1/ 1 -√2 * 1+ √2 / 1+√2
1/ x = 1+ √2 / -1 --------------(1)
now , putting the value
( x + 1/ x ) ³.
=> (1-√2 -(1+√2 )/-1)³.
( 1-√2 +1 + √2 )
=> ( 1+1) ³
=> 8.
=> 8
hence your answer is 8
hope it helps you dear !!
