Question

how many significant figures are in this number? 3670000

Explanation:

Significant figures: Non - zero digits are significant. Trailing zeros in a whole number without a decimal are not significant (they are just placeholders).

Step2: Analyze the number 3670000

The non - zero digits are 3, 6, and 7. The trailing zeros (the four zeros at the end) are placeholders and not significant. So we count the non - zero digits.
