Question

Use the order of operations to simplify the expression: 2^3 + 5 × 10 ÷ 2 – 3^3 + (11 – 8) Question 5 options: A)9 B)10 C)41 D)55 my answer when I worked it ended up being 3. Clearly, that’s not a choice

Answer 1

For this case we have that according to the order of PEMDAS algebraic operations, it is established that:

P: Any calculation is made inside the parentheses, making the most internal ones first.

E: Any exponential expressions are simplified.

MD: All the multiplications and divisions are made, from left to right, as they appear.

AS: All sums and subtractions are made, from left to right, as they appear.

So:

`2 ^ 3` + 5 * 10 ÷ 2-
`3 ^ 3` + (11-8) =

`2 ^ 3`+ 5 * 10 ÷ 2-
`3 ^ 3` + 3 =

8 + 5 * 10 ÷ 2-27 + 3 =

8 + 50 ÷ 2-27 + 3 =

8 + 25-27 + 3 =

33-27 + 3

6 + 3 =
