Chapter L, Problem 23PS

(a)

Interpretation Introduction

Interpretation: The correct number of significant figure has to be given.

Concept introduction:

Scientific notation expression: A number is expressed as the product of two numbers:${\text{N×10}}^{\text{n}}{\text{,where N is the digit term, 10}}^{\text{n}}\text{ is the exponential term}\text{.}$

Significant of zeroes:

• Zeroes between two other significant digits are significant.
• Zeroes to the right of a nonzero number, and also to the right of decimal place, are significant.
• Zeroes that are placeholders are not significant.
