Specify the solving method
1
Simplify $\sqrt{x^2}$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $2$ and $n$ equals $\frac{1}{2}$
$\lim_{x\to5}\left(\frac{\left(x+\sqrt{25}\right)\left(\sqrt{x^2}-\sqrt{25}\right)}{x-5}\right)$
2
Calculate the power $\sqrt{25}$
$\lim_{x\to5}\left(\frac{\left(x+5\right)\left(\sqrt{x^2}-\sqrt{25}\right)}{x-5}\right)$
3
Simplify $\sqrt{x^2}$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $2$ and $n$ equals $\frac{1}{2}$
$\lim_{x\to5}\left(\frac{\left(x+5\right)\left(x-\sqrt{25}\right)}{x-5}\right)$
4
Calculate the power $\sqrt{25}$
$\lim_{x\to5}\left(\frac{\left(x+5\right)\left(x- 5\right)}{x-5}\right)$
5
Multiply $-1$ times $5$
$\lim_{x\to5}\left(\frac{\left(x+5\right)\left(x-5\right)}{x-5}\right)$
6
Simplify the fraction $\frac{\left(x+5\right)\left(x-5\right)}{x-5}$ by $x-5$
$\lim_{x\to5}\left(x+5\right)$
7
Evaluate the limit $\lim_{x\to5}\left(x+5\right)$ by replacing all occurrences of $x$ by $5$
$5+5$
8
Add the values $5$ and $5$
