Question

Simplify: (2 + 1)^2 Plz

Answer 1

We have to use the order of operations to solve this equation.

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

The equation:
(2+1)²

So first, let's do 2+1, since it's in parentheses and you have to do parentheses first in the order of operations.
2+1 = 3

Now all we have left is:
3²

Then exponents:
3² = 9

The answer is 9.
