" 2.If "x+(1)/(x)=2," then "x^(3)+(1)/(x^(3))=

If x+(1)/(x)=2, then x^(3)+(1)/(x^(3))=64(b)14(c)8(d)2

If x = 4 +sqrt(15) . Find the value of x^(2) +(1)/(x^(2)) and x^(3) + ( 1)/(x^(3))

If the x= 5 +2sqrt6 find the value of x^(2) + (1)/(x^(2)) and x^(3) + (1)/(x^(3))

If x = sqrt7 + sqrt6 , then find the simpliest value of (a) x - (1)/(x) , (b) x + (1)/(x) , (c) x^(2) + (1)/(x^(2)) , (d) x^(3) + (1)/(x^(3))

If x+(1)/(x)=3, calcuate x^(2)+(1)/(x^(2)),x^(3)+(1)/(x^(3)) and x^(4)+(1)/(x^(4))

Find the sum of (x + (1)/(x))^(2), (x^(2) + (1)/(x^(2)))^(2), (x^(3) + (1)/(x^(3)))^(2) , ……..to n terms

If x ne 0 and x + (1)/(x) = 2 , then show that: x^(2)+ (1)/(x^(2))= x^(3) + (1)/(x^(3)) = x^(4) + (1)/(x^(4))

The sum of first 10 terms of the series : (x+(1)/( x))^(2) + ( x^(2) + ( 1)/( x^(2)))^(2) + ( x^(3)+ ( 1)/( x^(3)))^(2) + "......" is :
