Chapter 2, Problem 5PE

(a)

Interpretation Introduction

Interpretation:

The significant zeros in $\text{2050}$ has to be given.

Concept Introduction:

Significant figures:  The digits that are measured in a number including one estimated digit are called as significant figures.

All nonzero digits are always significant.

Exact numbers are always significant.

Rules for determining when a zero is a significant figure:

Rule 1:  A zero is considered as a significant figure when it is seen between two nonzero digits and at the end of a number with a decimal point.

Rule 2  A zero is not considered as a significant figure when it is seen at the beginning of a number and the end of a number, which does not contain a decimal point.
