Question

Evaluate the exponential expression and enter your answer .>
3*(5+ 4)^2 -4^2 ? help plz thank you :)

Answer 1

\[ 3(5 + 4)^2 - 4^2 \]
Like that?

Answer 2

I think it goes, "[P]lease [E]xcuse [M]y [D]ear [A]unt [S]ally" for order of evaluating
P = Parentheses
E = Exponents
D, M = Division and Multiplication
A, S = Addition and Subtraction

Answer 3

so...
\[ \begin{split}
3(5+4)^2 - 4^2 &~~~~~~~~~~~~~~Evaluate~parentheses~first\\
3(9)^2 - 4^2 &~~~~~~~~~~~~~~Now~exponents\\
3(81) - 16 &~~~~~~~~~~~~~~Then~we~multiply\\
243 - 16 &~~~~~~~~~~~~~~And~lastly~we~subtract\\
227&~~~~~~~~~~~~~~and~we're~done!\\
\end{split} \]
