Question

Calcula el valor de los siguientes límites​

Answer 1

lim. √2-√x =

x-->2. 4-x^2

lim. (√2-√x)(√2+√x) =

x-->2. (2-x)(2+x)(√2+√x)

lim. (2-x). =

x-->2. (2-x)(2+x)(√2+√x)

lim. 1. =

x-->2. (2+x)(√2+√x)

=. 1. = 1/(8√2)

(2+2)(√2+√2)

=(1.√2)/(8√2.√2)=√2/16

==>

lim. √2-√x = √2/16

x-->2. 4-x^2
