Here's our expression: [tex]3*(5+4)^{2}-4^{2}[/tex]
We will follow the order of operations and begin by solving everything in parentheses. [tex]3*9^{2}-4^{2}[/tex]
Next, we solve the exponents. [tex]3*81-16[/tex]
Now, we solve the multiplication and division. There is no division, so we will just solve the multiplication. [tex]243-16[/tex]
Finally, we solve the addition and subtraction. Since there is no addition, we will solve the subtraction. [tex]\boxed{227}[/tex]
