To arrange the numbers in ascending order, we can compare their values. Let's convert all the numbers to decimal form for easier comparison:
- \( 3.25 \times 10^{-4} = 0.000325 \)
- \( 1.25 \times 10^{-3} = 0.00125 \)
- \( 2.25 \times 10^{-3} = 0.00225 \)
- \( 3.25 \times 10^{-3} = 0.00325 \)
Now, placing these in ascending order:
- \( 0.000325 \) (or \( 3.25 \times 10^{-4} \))
- \( 0.00125 \) (or \( 1.25 \times 10^{-3} \))
- \( 0.00225 \) (or \( 2.25 \times 10^{-3} \))
- \( 0.00325 \) (or \( 3.25 \times 10^{-3} \))
Thus, the numbers arranged in ascending order are:
\( 3.25 \times 10^{-4}, 1.25 \times 10^{-3}, 2.25 \times 10^{-3}, 3.25 \times 10^{-3} \)
So the correct answer is: 3.25 × 10−4, 1.25 × 10−3, 2.25 × 10−3, 3.25 × 10−3.
