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.
