Given Hexadecimal $0$x$9$ABC$16$

$1)$ What is the binary representation? $($No steps needed for this one$)$

$2)$ Convert it to decimal number if this is an unsigned $16-$bit integer$$s binary representation.

$3)$ Convert it to decimal number if this is a $2$s$-$complement $16-$bit signed binary representation

to $32-$bit if it is an unsigned integer. Give result in both binary and Hex.

$5)$ Extend it to $32-$bit if it is a signed integer,. Give result in both binary and Hex.
