• Convert the sentence in the hexadecimal notation from the above table.

$\begin{array}{c}T=54\\ h=68\\ e=65\\ =20\end{array}$

$\begin{array}{c}t=74\\ o=6F\\ t=74\\ a=61\end{array}$

$\begin{array}{c}I=6C\\ =20\left(\text{space}\right)\\ c=63\\ o=6F\end{array}$

$\begin{array}{c}s=73\\ t=74\\ =\end{array}$
