Final Answer

indeterminate

Step-by-step Solution

Specify the solving method

1

Evaluate the limit $\lim_{x\to4}\left(\frac{3-\sqrt{5+x}}{1-\sqrt{5-x}}\right)$ by replacing all occurrences of $x$ by $4$

$\frac{3-\sqrt{5+4}}{1-\sqrt{5-4}}$
2

Subtract the values $5$ and $-4$

$\frac{3-\sqrt{5+4}}{1-\sqrt{1}}$
3

Add the values $5$ and $4$

$\frac{3-\sqrt{9}}{1-\sqrt{1}}$
4

Calculate the power $\sqrt{1}$

$\frac{3-\sqrt{9}}{1-1}$
5

Subtract the values $1$ and $-1$

$\frac{3-\sqrt{9}}{0}$
6

Calculate the power $\sqrt{9}$

$\frac{3-1\cdot 3}{0}$
7

Multiply $-1$ times $3$

$\frac{3-3}{0}$
8

Subtract the values $3$ and $-3$

$\frac{0}{0}$
9

$\frac{0}{0}$ represents an indeterminate form
