Explanation:

In scientific notation, we write a number so that it has single digit to the left of decimal sign and is multiplied by an integer power of

10

.

Note that moving decimal

p

digits to right is equivalent to multiplying by

10

p

and moving decimal

q

digits to left is equivalent to dividing by

10

q

.

Hence, we should either divide the number by

10

p

i.e. multiply by

10

p

(if moving decimal to right) or multiply the number by

10

q

(if moving decimal to left).

In other words, it is written as

a

×

10

n

, where

1

a

<

10

and

n

is an integer.

To write

0

,

0045

in scientific notation, we will have to move the decimal point three point to right, which literally means multiplying by

1000

=

10

3

.

Hence in scientific notation

0.0045

=

4.5

×

10

3

(note that as we have moved decimal three point to right we are multiplying by

10

3
