Part 1
Find the value of the expression.
5 squared left bracket left parenthesis 9 plus 18 right parenthesis minus 16 right bracket

Answer 1

To find the value of the expression \( 5^2 \left[ (9 + 18) - 16 \right] \), we can break it down into steps:

1. Calculate \( 5^2 \):
\[
5^2 = 25
\]

2. Evaluate the expression inside the bracket:
\[
(9 + 18) = 27
\]
Then subtract 16:
\[
27 - 16 = 11
\]

3. Now, substitute back into the expression:
\[
25 \left[ 11 \right] = 25 \times 11
\]

4. Finally, calculate \( 25 \times 11 \):
\[
25 \times 11 = 275
\]

So, the value of the expression is \( \boxed{275} \).
