Help, teachers asking me to do this independently but I barely understand. Help ASAP!!!

Answer 1

9

Explanation:

Use PEMDAS to solve it.

2 3 - (8-4) + 5 =

First: 2 3 - (4) + 5 =

Second: solve the 2 to the power of 3 exponent

2×2×2=8 (2×2=4 then 4×2=8)

So, 8 - 4 + 5 =

Third: 4 + 5 =

Last: 9

Answer 2

`{{\rm{ {2}^(3) - (8 - 4) + 5 }}}`

`{{\rm{\implies \: calculate \: the \: power}}}`

`{{\rm{ {2}^(3) = 8 }}}`

`{{\rm{ 8 - (8 - 4) + 5}}}`

`{{\rm{ 8 - 4 + 5}}}`
