Question

what is 0.005 in standard form?

Answer 1

Answer:

5 × $10^{-3}$

Step-by-step 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 × $10^{-3}$

Answer 2

$\\ \sf\Rrightarrow 0.005$

• Cancel 0s one by one

$\\ \sf\Rrightarrow 0.05\times 10^{-1}$

$\\ \sf\Rrightarrow 0.5\times 10^{-2}$

$\\ \sf\Rrightarrow 5\times 10^{-3}$
