Question

ME AJUDE, POR FAVOR
limite de 2 variaveis lim x-y / raiz x - raiz y (x,y) tendendo a (3,3)

Answer 1

Lim (x-y)/(√x-√y)

(x,y)-->(3,3)

Lim (x-y)(√x+√y)/(√x-√y)(√x+√y)

(x,y)-->(3,3)

Lim (x-y)(√x+√y)/(√x²-√y²)

(x,y)-->(3,3)

Lim (x-y)(√x+√y)/(x-y)

(x,y)-->(3,3)

Lim (√x+√y)  =√3+√3 =  2√3

(x,y)-->(3,3)
