$4$

Start from the inner bracket. The multiplication did not really need to be in a bracket, because multiplication is done before addition.

$2[color(red)((2xx3))+10]div8$

= $2[color(red)(6)+10]div8$

Once we have $(2 xx16)/8$ , there are many options for simplifying:

= $(2 xx16)/8 = (2 xxcancel16^2)/cancel8 = 2xx2 = 4$
OR

$(2 xx16)/8 = 32/8 = 4$

OR

$(2 xx16)/8 = (cancel2 xx16)/cancel8^4 = 16/4 = 4$
