question 9 (1 point)
how many significant digits does the following number have?
23 000 100
only type the number of digits in the blank below (ex. 8)

Explanation:

Step1: Recall significant - digits rule

Non - zero digits are always significant.

Step2: Analyze the number 23000100

The non - zero digits 2, 3, 1 are significant. The zeros between non - zero digits (the zero between 3 and 1) is significant, and the leading zeros are not significant. Trailing zeros without a decimal point may or may not be significant, but in this case, we count all digits for the count of significant digits.
