Using the given operators, decide whether the following expressions $(($a$)$ to $($e$))$ are ty$-$

peable or not. If the expression is typeable $($able to be reduced to a typed expression$),$ give

its type and expected output. Otherwise, give an explanation of why it is not typeable.

$1.!(5>3)$

$2.100/$ x; given x $=$ "twenty"

$3.45\mathrm{.}0+19\mathrm{.}0$

$4.45*(3>2)$

$5.99\mathrm{.}0==(50\mathrm{.}0+49\mathrm{.}0)$
