Written in scientific notation, to three significant digits, the number 12 587 is_______?______ x 10?

If that number is 12 587 (twelve thousand five hundred eighty seven) or 12,587, then 12,600 to three significant figures or

1.26 x 10^4 in scientific notation.

Written in scientific notation, to three significant digits, the number 12 587 is_______?______ x 10?

To write the number 12 587 in scientific notation to three significant digits, we need to move the decimal point four places to the left. This results in the number 1.26 x 10^4.

To write the number 12,587 in scientific notation, we need to express it as a number between 1 and 10 multiplied by a power of 10.

Step 1: Count the number of digits in the original number. In this case, there are 5 digits (12,587).

Step 2: Move the decimal point in the original number so that there is only one non-zero digit to the left of the decimal point. We move the decimal point three places to the left, resulting in 1.2587.

Step 3: Determine the power of 10 by counting how many places we moved the decimal point in step 2. In this case, we moved the decimal point three places to the left, so the power of 10 is 10^3.

Therefore, written in scientific notation to three significant digits, the number 12,587 is 1.26 x 10^4.
