" 13."4faquad 3x+(1)/(2x)=5" bt,ail "8x^(3)+(1)/(27x^(3))

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

If 3x + (1)/(3x) = 3 , find : (ii) 27x^3 + (1)/( 27x^3)

If 3x+(1)/(2x)=5 then what is the value of 27x^(3)+(1)/(8x^(3)) ?

If x ne 0 and 3x +(1)/(3x)= 8, find the value of :27 x^(3) + ( 1)/(27x^(3))

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

Factorize: (8)/(27)x^(3)+1+(4)/(3)x^(2)+2x

If int(sqrt(1-x^(2)))/(x^(4))dx=A(x)*(sqrt(1-x^(2)))^(m) where A(x) is a function of x then (A(x))^(m)= (A) -(1)/(27x^(9))(B)(1)/((27x)^(9))(C)(1)/(3x^(9))(D)-(1)/(3x^(9))
