If `frac{a}{b}+frac{b}{a}=2` then the value of (a-b) is

If [a b c]=2 , then find the value of [(a+2b-c)(a-b)(a-b-c)] .

If a+b=7 and a b=12 , find the value of (a^2-a b+b^2)

If a+b=7 and a b=12 , find the value of (a^2-a b+b^2)

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 (a)/(b)=2, what is the value of (4b)/(a) ?

IF a^b=4 and 3b=2, what is the value of a?

If (a-b)/(b)=(2)/(3) , what is the value of (a)/(b) ?

If a : b=2:5, . find the value of (3a+2b)/(4a+b)
