Question

evaluate
give solution​

Answer 1

Answer:

-1/3

Step-by-step explanation:

Explanation:

lim. 3−√5+x

x→4. 1−√5−x

The limit has 0/0 uncertainty. After multiplying both sides with conjugates of denominator and numerator,

lim. (3−√5+x) (3+√5+x) (1+√5−x)

x→4. (1−√5−x) (3+√5+x) (1+√5−x)

= lim. [3^2−(5+x)](1+√5−x)

x→4. [1^2−(5−x)](3+√5+x)

= lim. (4−x)(1+√5−x)

x→4. (x−4)(3+√5+x)

= lim. −(x−4)(1+√5−x)

x→4 (x−4)(3+√5+x)

= lim. −1+√5−x

x→4. 3+√5+x

= −2/6

= −1/3

hope it may helped uhh
