If `frac{x}{6}=frac{7}{-3}`,then the value of x is

If x+1/x=3 , then the value of x^6+1/x^6 is.

If f(x)=x^3-frac{1}{x^(3)} find the value of f(x)+f(frac{1}{x})

If int frac{xdx}{x^2-4x+8}=K log (x^2-4x+8)+tan^(-1)(frac{x-2}{2})+C , then the value of K is:

If [2x+y,4x,5x-7 4x]=[7 7y-13 y x+6] , then the value of x+y is x=3 , y=1 (b) x=2 , y=3 (c) x=2 , y=4 (d) x=3 , y=3

[{:(2x+y,4x),(5x-7,4x):}]=[{:(7,7y-13),(y,x+6):}] then the value of x,y is

If the maximum and minimum values of y=(x^2-3x+c)/(x^2+3x+c) are 7 and 1/7 respectively then the value of c is equal to (A) 3 (B) 4 (C) 5 (D) 6

If 3^(((log_3 7))^x)=7^(((log_7 3))^x) , then the value of x will be

if 3x-7=9, what is the value of 6x+5?

If |(2x,5),(8,x)|=|(6,-2),(7,3)| then the value of x is
