Question

How do you find `1^ { 5} + 2^ { 3} \div 4`?

Answer 1

Use the order of operations. PEMDAS

Explanation:

To remember the order of operations think about " if you get hurt in
(PE get a Medical Doctor As Soon as possible.)

PE is one class so do parenthesis and exponents together
MD a doctor is one person so do Multiplication and Division together working from left to right.
AS as soon as possible is one time so do Addition and Subtraction together working from left to right.

Start with Parenthesis and Exponents. There is no parenthesis so starting with the exponents.

`1^5 = 1`
`2^3 = 8`

putting these values in place of the exponents gives

`1 + 8 / 4`

Next do division and multiplication,

`8/4 = 2`

putting the 2 in place of `8/4` gives

`1 +2`

Next do addition and subtraction so

`1 + 2 = 3`
