To express 2 × 3^2 × 7 as a whole number, we can simplify the expression step by step.
Step 1: Evaluate 3^2.
3^2 means 3 raised to the power of 2, which is 3 × 3 = 9.
Step 2: Multiply 2 × 9.
2 × 9 = 18.
Step 3: Multiply 18 by 7.
18 × 7 = 126.
Therefore, the whole number expression for 2 × 3^2 × 7 is 126.
To express 2 × 3^2 × 7 as a whole number, we need to simplify the expression by performing the operations in the correct order.
The first step is to evaluate the exponent, which means raising 3 to the power of 2: 3^2 = 9.
Next, multiply the result (9) by 2: 9 × 2 = 18.
Finally, multiply the obtained value (18) by 7: 18 × 7 = 126.
So, the correct answer is 126.
