If `x-1/x=1` , then the value of `x^3-1/(x^3)` is equal to (a) 2 (b) 3 (c) 4 (d) 8

If (x-1)/(x)=3, then the value of 1+(1)/(x^(2)) is (a) 9(b) 10(c)11 (d) None of these

Find the value of x if 2^(x-3)=1 (a) 1 (b) 2 (c) 3 (d) 4

If x=root(3)(7+5sqrt(2))-(1)/(root(3)(7+5sqrt(2))), then the value of x^(3)+3x-14 is equal to 1(b)0(c)2 (d) 4

If sec x+sec^(2)x=1 then the value of tan^(8)x-tan^(4)x-2tan^(2)x+1 will be equal to 0(b)1(c)2(d)3

1/3+1/x=3 , then x= 7/3 (b) 2/3 (c) 4/3 (d) 8/3

if x+(1)/(4x)=(3)/(2) find the value of 8x^(3)+(1)/(8x^(3))

If X^2+4x+3=0 , then the value of (X^3)/(X^6+27x^3+27 is (A) -1 (B) -frac(1)(2) (C) 1 (D) 1/2
