Question

Evaluate the expression below 3^3-10+(2*4^2)

Answer 1

49

Explanation:

We are going to use PEMDAS to simplify

`3^3-10+(2 \cdot 4^2)`

First step is P.

P refers to the parenthesis or anything acting as a grouping symbol.

We notice the following operations there are multiplication and exponents.

According to PEMDAS, after parenthesis we do the exponents so let's do the exponent in the ( ).

`3^3-10+(2 \cdot 16)`

Now we still have to finish P up. That is we need to do the one last operation in the ( ).

`3^3-10+(32)`

Nothing left to perform in the () so we can just write:

`3^3-10+32`

Now there are no more grouping symbols left.

The next letter is E and it stands for exponents so we must evaluate anything we can that has an exponent.

`27-10+32`

Now after E we have M and D which means to multiply and divide as you the expression from left to right.

There is no multiplication and division so moving on.

A and S means to do the addition and subtraction as it occurs left to right:

`17+32`

`49`
