Answer:

83

Explanation:

Due to the PEMDAS rule, brackets will have to go first.
#8+5[color(red)(10+10div2)]#
If a number has already been given after solving a problem that was in brackets, a multiplication sign should be there before the answer. So it will be this:
#8+5xxcolor(red)(15)#
There aren't any exponents, but there is multiplication, so it'll go next.
#8+color(red)(5xx15)#
So it will be this:
#8+color(red)(75)#
Finally, we will have to do addition.
#color(red)(8+75)#
So the final answer is 83. Hope this helped!
