`(5-x)/(5+x)`

If x +(frac(1)(x))=15 , then find the value of (5x)/(5x^2 - 11x +5)

The value of lim_(xrarr0)(sin 5x)/(5x) is ………

lim_(xrarr5)(sqrt(x+5)-sqrt(x-5))/(x+5) is equal to

Value of x satisfying the equation (log_(5)(x))^(2)+log_(5x)((5)/(x))=1 are

Suppose a,b,c,gt 1 and f(x)=|(a^(-x),a^(x),x),(b^(-3x),b^(3x),3x^(3)),(c^(-5x),c^(5x),5x^(5))|, x epsilon R then f is

log_e ((1+3x)/(1-2x)) is equal to a) -5x-(5x^2)/2-(35x^3)/3-... b) -5x+(5x^2)/2-(35x^3)/3-... c) 5x-(5x^2)/2+(35x^3)/3-... d) 5x+(5x^2)/2+(35x^3)/3-...

Lt_(x to 5) (|x-5|)/(x-5)=

Find the limits lim_(x to 5) (-|x-5|)/((x-5))
