`x^4+(4)/(x^4)`

lim_(xto0)(sinx^(4)-x^(4)cosx^(4))/(x^(4)(e^(2x^(4))-1-2x^(4))) is

lim_(x rarr0)(sin x^(4)-x^(4)cos x^(4))/(x^(4)(e^(2x4)-1-2x^(4)))(1)/(3) b.(1)/(2) c.(1)/(6)d.2

(4x+5)/(4x) = (4x)/(4x) + 5/(4x) = 1+5/(4x)

If x = (8ab)/(a+b) , then find the value of ((x+4a)/(x - 4a) + (x+4b)/(x-4b)) .

If x=(8ab)/(a+b) the value of (x+4a)/(x-4a) + (x+4b)/(x-4b)

lim_(x rarr 4^(-)) (|x-4|)/(x-4)= ________.

int (x dx)/(4x^(4)+4x^(2)+5)

f(x)={(x-4)/(|x-4|)+a,quad if x<4a+b,quad if x=4(x-4)/(|x-4|)+b,quad if x is continuous at x=4, find a,b .
