#38#.

To solve this use the order of operations, which means you solve the following in order from left to right in an expression:

Grouping symbols

Exponents

Multiplication/division

Addition/subtraction


Evaluate inside the parentheses first:

#16+[9\times(color(red)(4))+8]\div2#

Then evaluate the multiplication inside the brackets:

#16+[color(red)(36)+8]\div2#

Add within the brackets:

#16+[color(red)(44)]\div2#

Divide by #2#:

#16+color(red)(22#

#=38#
