If `underset(xrarra)Lt(x^5-a^5)/(x-a) = 405`. Find all possible values of a.

underset(xrarra)lim (x^n-a^n)/(x-a) is equal to:

Evaluate: underset(xrarra)lim ((x+2)^(5/3)-(a+2)^(5/3))/(x-a) .

Find all roots of X^(5)-1=0.

Evaluate: underset(xrarr0)lim(sin5x)/(sin8x)

True or False : If underset(x rarr a)Lt f(x)g(x) exists then both underset(xrarra^+)Lt f(X) and underset(xrarra^-) Lt g(x) exist separately.

Evaluate: underset(xrarra)lim [(x+2)^(3/2)-(a+2)^(3/2)]/(x-a) .

Evaluate: underset(xrarr5)lim (1-sqrt(x-4))/5 .

If x_1,x_2,………….x_p are p values of variabled x such that underset(i=1)overset(p)sum(x_i-2)=110 and underset(i=1)overset(p)sum(x_i-5)=20 find the value of p and the mean.

If (x - 2,y + 3) = (5,-6) , then find the value of x and y.
