Answer:

=13

*The answer must have a positive sign.*

Explanation:

This question's it's about the order of operations. It stands for parenthesis, exponents, multiply, divide, add, and subtract. It can also go left too right. (PEMDAS)

First, do parenthesis.

Then, do exponents first.


(3^2-4)


3^2=3*3=9


8+9-4

Next, add/subtract left too right.


8+9=17


17-4=13

Answer: →
=13

Hope this helps!

Thanks!

Hey there!

In order for you to solve this equation you could do
PEMDAS, which is ↓


  • Parentheses

  • Exponents

  • Multiplication

  • Division

  • Addition

  • Subtraction

In this particular equation we have ↓


  1. Parentheses

  2. Exponents

  3. Addition

  4. Subtraction

So, the first thing we need to do to solve this equation is solve what is in the
parentheses


(3^2 - 4)

Nextly, we have to do the
exponents


3^2

So, let's solve the
parentheses &
exponents


3^2
=
9

We could now "remove" the
parentheses


9 - 4
=
5

Now we could move onto the last step, which is
addition


8+5
=
13


\boxed {Answer: 13}

Good luck on your assignment and enjoy your day!
