16÷(-2)x 4 OVER 2^3 +4
I have no idea of how to do this
This was answered last night.
look at the numerator.
sixteen divided by -2. That is -8. Times 4, that is -32.
The denominator: 2^3 is eight, add 4, that is 12
Now, -32/12 is what?
Again, it is hard to see where your fractions end. I assume the +4 is in the d enominator.
I think you need a tutor just on the grouping and order of operations part.
thanks
so 2 2/3 ia my answer correct?
To solve this expression, we can follow the order of operations, which is commonly known as PEMDAS ( Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
Let's break down the expression step by step:
1. Exponents:
- Evaluate 2^3: 2^3 = 2 x 2 x 2 = 8
2. Multiplication and Division (from left to right):
- Divide 16 by -2: 16 ÷ (-2) = -8
- Now multiply -8 by 4: -8 x 4 = -32
3. Addition and Subtraction (from left to right):
- Add 4 to the result obtained in the previous step: -32 + 4 = -28
4. Lastly, let's address the division symbol "÷" which is interpreted as multiplying by the reciprocal:
- Multiply -28 by 1/8 (inverse of 2^3): -28 x (1/8) = -28/8 = -7/2 or -3.5
So the final answer to the expression 16 ÷ (-2) x 4 ÷ 2^3 +4 is -3.5 or -7/2.
It's important to note that taking proper care of parentheses, exponents, and following the order of operations is crucial when evaluating mathematical expressions.
