This problem is in chapter 9 page 708, problem 58. It looks like it could be solved two ways.
16 div. by (-2)*(-4)
---------------------
2^ +4
16 div. by (-2)*(-4)
16/8 = ?
To solve this problem, we need to follow the order of operations (PEMDAS/BODMAS).
First, let's simplify the expression in the numerator: 16 divided by (-2) multiplied by (-4).
Step 1: Divide 16 by (-2). The division of a positive number by a negative number yields a negative result. So, 16 divided by (-2) is equal to -8.
Step 2: Multiply -8 by (-4). When you multiply two negative numbers, the result is positive. So, -8 multiplied by (-4) is equal to 32.
Now, let's simplify the expression in the denominator: 2 squared (2^2) plus 4.
Step 3: Calculate 2 squared (2^2). Two squared is equal to 2 multiplied by 2, which is 4.
Step 4: Add 4 to 4. The sum is 8.
Now, we can rewrite the expression as:
32
--
8
To simplify further, we divide the numerator (32) by the denominator (8).
Step 5: Divide 32 by 8. The result is 4.
Therefore, the solution to the problem is 4.
