WRITE THE GIVEN PRODUCT EXPRESSION AS WHOLE NUMBER

Exponents are used to avoid the repetition of writing the same numerical values many times.

Example 1  :

2 × 3 × 5

Solution :

=  2 × 3 × 5

By converting it as whole number, we get

=  6 × 5

=  30

So, the whole number is 30.

Example 2 :

2² × 5

Solution :

=  2² × 5

2² written as 2 × 2

By converting it as whole number, we get

=  2 × 2 × 5

=  20

So, the whole number is 20.

Example 3 :

2³ × 7

Solution :

=  2³ × 7

2³ written as 2 × 2 × 2

By converting it as whole number, we get

=  2 × 2 × 2 × 7

=  56

So, the whole number is 56.

Example 4 :

2 × 3³ × 5

Solution :

Given,

2 × 3³ × 5

3³ written as 3 × 3 × 3

By converting it as whole number, we get

=  2 × 3 × 3 × 3 × 5

=  270

So, the whole number is 270.

Example 5 :

2² × 3² × 11

Solution :

=  2² × 3² × 11

2² and 3² written as 2 × 2 and 3 × 3

By converting it as whole number, we get

=  2 × 2 × 3 × 3 × 11

=  396

So, the whole number is 396.

Example 6 :

2³ × 5² × 11²

Solution :

=  2³ × 3² × 11²

2³  =  2 × 2 × 2

3²  =  3 × 3

11²  =  11 × 11

By converting it as whole number, we get

=  2 × 2 × 2 × 3 × 3 × 11 × 11

=  8712

So, the whole number is 8712.
