Question

Help for number 10 please

Answer 1

Start with

`4(3^3-8) / 2`

Exponents have the highest priority, so we evaluate 3 cubed first:

`4(27-8) / 2`

Next, we have to solve parenthesis first: we have 27-8 = 19, so the expression becomes

`4 * 19 / 2`

Multiplications and divisions have the same priority, so we perform them as they appear:
`4 * 19 = 76`, so the expression becomes

`76 / 2 = 38`
