Question

What is 0.005 in standard form?

Answer 1

`\\ \sf\Rrightarrow 0.005`

• Cancel 0s one by one

`\\ \sf\Rrightarrow 0.05* 10^(-1)`

`\\ \sf\Rrightarrow 0.5* 10^(-2)`

`\\ \sf\Rrightarrow 5* 10^(-3)`

Answer 2

5 ×
`10^(-3)`

Explanation:

A number in standard form is

a ×
`10^(n)`

where 1 ≤ a > 10 and n is an integer

Given

0.005 ← express as a number between 1 and 10

= 5 ×
`10^(n)`

n is the value required to move the decimal point back to its original position

A move to the right is +

A move to the left is -

Here we require to move the decimal point back 3 places to the left

Thus

0.005 = 5 ×
`10^(-3)`
