" (ii) "quad x-(1)/(x)=8

" 1.Solve for x : (1)/((x-2))+(1)/(x)=(8)/((2x+5))

If x^(2)+(1)/(x^(2))=102, then x-(1)/(x)=8( b) 10 (c) 12 (d) 13

(x+(1)/(x))(x-(1)/(x))(x^(2)+(1)/(x^(2))-1)(x^(2)+(1)/(x^(2))+1) is equal to x^(6)-(1)/(x^(6))(b)x^(8)-(1)/(x^(8))(c)x^(6)+(1)/(x^(6))(d)x^(8)+(1)/(x^(8))

2^(x+1)+4^(x)=8

If ( x^(8) + ( 1)/( x^(8)))= 47 , what is the value of ( x^(6) + ( 1)/( x^(6))) ?

If x^(8)+(1)/(x^(8))=a then find (i)x+(1)/(x)

If quad (1+x)(1+x^(2))(1+x^(4))(1+x^(8))1+x^(2)^^nquad find (dy)/(dx)

If x + 1/x = 8 and x - 1/x = -8 , then find the value of x^2 - 1/(x^2)
