$\begin{align*} c^2 &= a^2 + b^2 \\ c^2 &= 6^2 + 8^2 \\ 
c^2 &= 36 + 64 \\ \sqrt{c^2} &= \sqrt{100} \\ c&=10 \end{align*}$

$$\begin{aligned*} c^2 &= a^2 + b^2 \\ c^2 &= 6^2 + 8^2 \\ 
c^2 &= 36 + 64 \\ \sqrt{c^2} &= \sqrt{100} \\ c&=10\end{aligned*}$$

$\begin{aligned} c^2 &= a^2 + b^2 \\ c^2 &= 6^2 + 8^2 \\ 
c^2 &= 36 + 64 \\ \sqrt{c^2} &= \sqrt{100} \\ c&=10 \end{aligned}$

$\begin{align} c^2 &= a^2 + b^2 \\ c^2 &= 6^2 + 8^2 \\ 
c^2 &= 36 + 64 \\ \sqrt{c^2} &= \sqrt{100} \\ c&=10 \end{align}$

$$\begin{aligned} c^2 &= a^2 + b^2 \\ c^2 &= 6^2 + 8^2 \\ 
c^2 &= 36 + 64 \\ \sqrt{c^2} &= \sqrt{100} \\ c&=10 \end{aligned}$$
