Answer:

4

Explanation:

Key concept: Significant figures in the measured value of a physical quantity tell the number of digits in which we have confidence. Larger the number of significant figures obtained in a measurement, greater is the accuracy of the measurement. The reverse is also true.

The following rules are observed in counting the number of significant figures in a given measured quantity.

1. All non-zero digits are significant.

2. A zero becomes significant figure if it appears between two non-zero digits.

3. Leading zeros or the zeros placed to the left of the number are never significant.

4. Trailing zeros or the zeros placed to the right of the number are significant.

5. In exponential notation, the numerical portion gives the number of significant figures.

Leading zeros or the zeros placed to the left of the number are never .
