Chapter 2, Problem 31E

Interpretation Introduction

Interpretation:

Each of the given numbers is to be expressed in scientific notation.

Concept Introduction:

Scientific notation is a scientific way of writing very large or small numbers.

It consists of two parts, a decimal and an exponential which is written as a decimal part multiplied by an exponential part.

The decimal part is a number between1 to 10.

An exponential part is an exponent raised to a power $\text{10}$

. It can be positive or negative.

A large number is converted to scientific notation by moving the decimal point to the left, until a number between 1 to 10 is obtained. This decimal number is $\text{N}$.

Then, the exponent $\left(n\right)$ is determined by counting the number of places the decimal point is being moved.

When moved to left, the exponent is a positive value.
