Question

How do you simplify `(5÷7^3) ÷ 7 times 7` using order of operations?

Answer 1

`5/343`

Explanation:

`(5 -: 7^3) -: 7 * 7`

PEMDAS (the order of operations) is shown here:

First, simplify the expression inside the parenthesis:
`(5 -: 343) -: 7 * 7`

`5/343 -: 7 * 7`

We know that dividing by a number then multiplying by the same number just means to multiply/divide by `1`, or doing nothing, so the answer is just `5/343`.
