Let's calculate the expression \( 2 \times 3^2 \times 7 \).
First, we compute \( 3^2 \):
\[
3^2 = 9
\]
Now, substitute \( 9 \) back into the expression:
\[
2 \times 9 \times 7
\]
Next, we calculate \( 2 \times 9 \):
\[
2 \times 9 = 18
\]
Now, we multiply \( 18 \) by \( 7 \):
\[
18 \times 7 = 126
\]
Thus, the whole number value of \( 2 \times 3^2 \times 7 \) is \( 126 \).
The correct response is:
126
