`limx→a(x^3−a^3)/(x−a)=`

limx→∞ tanx/x

x^(x^(3))+(x^(3))^(x)

The value of the determinant |(x, x+a, x+2a),(x,x+2a, x+4a),(x, x+3a, x+6a)| is (A) 0 (B) a^3-x^3 (C) x^3-a^3 (D) (x-a)^3

lim_(x rarr oo)((x-3)/(x+3))^(x+3)

int(x^(3)+3)/(x^(3)-3x)dx

(x/3-3/x)^3

Solve by factorization: (x-3)/(x+3)-(x+3)/(x-3)=(48)/(7),x!=3,x!=-3

Find the roots : (x-3)/(x+3) -(x+3)/(x-3)=0,(x != 3,-3)

Solve for x : (x+ 3)/(x + 2) = (3x -7)/(2x - 3) , x =2 , (3)/(2)
