16÷(-2)◦(-4)

______________
2³+ 4
16÷8
_______
8 + 4
2 = 1
12 6
There is supposed to be a line under the first part of the problem making it a fraction.

To solve this problem, you need to evaluate the given expression step-by-step. Let's start by rewriting the expression properly as a fraction:

16÷(-2)◦(-4)
______________
2³+ 4

Now let's simplify the numerator of the fraction by performing the division:

16÷(-2) = -8

Now let's simplify the denominator of the fraction by performing the exponentiation and addition:

2³+4 = 8 + 4 = 12

So the expression becomes:

-8
______
12

To simplify the fraction, you need to find the greatest common divisor (GCD) of the numerator and denominator, which is 4 in this case. Divide both the numerator and denominator by 4:

-8 ÷ 4 = -2
12 ÷ 4 = 3

So the simplified fraction is:

-2
___
3

Therefore, the solution to the expression 16÷(-2)◦(-4) / (2³+ 4) is -2/3.
