Answer» Required VALUE of x^6 + 1 / x^6 is 33385282. Step-by-step-explanation: Given, x = 9 - 4√5 = > x = 9 - 4√5 = > 1 / x = 1 / ( 9 - 4√5 ) USING Rationalisation : In right hand side , multiplying and dividing the original numerator and denominator by the original denominator but with the opposite signs between the rational and irrational terms. It means : Here, we have to multiply by 9 + 4√5. Therefore, From the properties of expansion : ( a + b )( a - b ) = a^2 - b^2 Then, = > x^6 + 1 / x^6 = > ( x^2 )^3 + ( 1 / x^2 )^3 = > ( x^2 + 1 / x^2 )( x^4 - x^2 / x^2 + 1 / x^4 ) { a^3 + b^3 = ( a + b )( a^2 - ab + b^2 ) } = > ( x^2 + 1 / x^2 )( x^4 - 1 + 1 / x^4 ) = > { ( x + 1 / x )^2 - 2( x × 1 / x ) }{ x^4 + 1 / x^4 - 1 } { ( a + b )^2 - 2ab = a^2 + b^2 } = > { ( x + 1 / x )^2 - 2 }{ x^4 + 1 / x^4 - 1 } = > { ( 9 - 4√5 + 9 + 4√5 )^2 - 2 } { ( x^2 )^2 + ( 1 / x^2 )^2 - 1 } = > { ( 18 )^2 - 2 }[ { ( x^2 + 1 / x^2 )^2 - 2 - 1 } { ( x^2 + 1 / x^2 )^2 - 2 = x^4 + 1 / x^4 } = > ( 324 - 2 )[ { ( x + 1 / x )^2 - 2 }^2 - 3 } = > ( 324 - 2 ){ { ( 9 - 4√5 + 9 + 4√5 )^2 - 2 }^2 - 3 } = > ( 322 ){ ( 18^2 - 2 )^2 - 3 } = > ( 322 )( ( 324 - 2 )^2 - 3 ) = > 322 ×( ( 322 )^2 - 3 ) = > 322 x 103681 = > 33,385,282 Hence the required value of x^6 + 1 / x^6 is 33,385,282. |

|
Answer» Step-by-step explanation: CP of 1ST thing (CP1) is 4500 PROFIT%=15% hence, SP of 1st thing(SP1)= 115%(4500) SP1=(115/100)×4500 SP1=5175 Profit on 1st item(P1)=SP1-CP1 P1=5175-4500 P1=675 he later buys new thing from money he GOT by sellung 1st item.. SP1 BECOMES CP2 of 2nd item..=5175 loss of 10% occurs 90%(CP2)=SP2 90%(5175)=SP2 4657.5=SP2 Loss on 2nd item is L2 CP2-SP2=5175-4657.5=517.5/- Totally he is in profit ZONE as P1>L2 total profit=675-517.5=157.5/-
