Answer:

D

Step-by-step explanation:

The expression is  [tex](9-7*3+4)^2[/tex]

We can follow the rule of "PEMDAS" here.

PEMDAS = Parenthesis, Exponents, Multiply, Divide, Add, Subtract

So, we first need to deal with Parenthesis. Next,

There aren't any exponents, so we deal with Multiplication of 7 and 3.

Then addition/subtraction.

Hence, the first step, from the answer choices, would be D, multiply 7 and 3
