For this problem, PEMDAS is really important, because we need to make sure that we are doing things in the correct order.
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
The first thing we need to do is the math inside the parentheses:
(1 + 1/3) = 1 + 1/3 = 4/3
Next, we square the parentheses:
(4/3)² = 16/9
Now, all we need to do is subtract!
16/9 - 2/9 = 14/9
If you need to make it a proper fraction, your answer is 1 5/9, but if you leave it improper then 14/9.
