If `(x+1/x)=sqrt(13)` , then the value of `(x^3-1/(x^3))` is (a) 26 (b) 27 (c) 30 (d) 36

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=(sqrt2 + 1 ) ^(-1//3) , then the value of (x^3 - frac(1) (x^3)) is (A) 0 (B) -sqrt2 (C ) -2 (D) 3sqrt2

If 3^(x)+3^(x+1)=36 , then the value of x^(x) is :

If (x+y)=13 and xy=36 , then the value of (x^(3)+y^(3)) is :

If area of an equilateral triangle inscribed in the circle x^(2)+y^(2)+10x+12y+c=0 is 27sqrt(3), then the value of c is (a) 25(b)-25 (c) 36(d)-36

If x=(7-4sqrt(3)), then the value of (x+(1)/(x)) is 3sqrt(3)( b 8sqrt(3)(c)14(d)14+8sqrt(3)

If (x+y)=13 and xy=36 then the value of (x^3+y^3) is:

If (x^(4)+(1)/(x^(4)))=322, the value of (x-(1)/(x)) is (a) 4(b)3sqrt(2)(c)6(d)8
