47.8x-(1)/(x)=3,x!=0

If x-(1)/(x)=5,xne0 then what is the value of (x^(6)+3x^(3)-1)/(x^(6)-8x^(3)-1) ?

If (2x)/(3y)+(3y)/(2x)=1,(x,y!=0), then the value of 8x^(3)+27y^(3) is

f(x)={(1+8x^(3),x 0) and g(x){(2x-1)^((1)/(3)),x<0,(1,x=0) and sqrt(2x+1),x Then define fog (x) and comments on the continuity of gof(x) at x=(1)/(2)

If 2x - (1)/(2x) =4 , find : (ii) 8x^(3) - (1)/( 8x^3)

If the function f(x) {((1 - cos 4x)/(8x^(2))",",x !=0),(" k,",x = 0):} is continuous at x = 0 then k = ?

If x + (1)/(2x)= 3 , find the value of 8x^(3) + (1)/(x^(3))

If x^(2)-3x+1=0 , then one of the values of (x^(2)-8x-1)/(x^(3)+1//x) is :

If x^(2)+(1)/(x^(2))=7 and x!=0: find the value of 7x^(3)+8x-(7)/(x^(3))-(8)/(x)

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