To find which number is 1,000 * larger than 2.3 * 10 ^2 you would do the following steps

To find a number that is 1,000 times larger than 2.3 * 10^2, you can follow these steps:

Step 1: Multiply 2.3 by 1,000: 2.3 * 1,000 = 2,300.

Step 2: Move the decimal point three places to the right in the result obtained from step 1 since we are dealing with a number in scientific notation. This step is necessary because multiplying by 1,000 increases the value of the number by three orders of magnitude: 2,300 becomes 2.3 * 10^3.

Therefore, the number that is 1,000 times larger than 2.3 * 10^2 is 2.3 * 10^3.
