An inch is approximately equal to 0.02543 metres. Write this distance in standard form.

Solution:

Given, an inch is approximately equal to 0.02543 metres.

We have to write the distance in standard form.

Now, 0.02543 metres = 2.543/100

Using law of exponents,

a⁻ⁿ = 1/aⁿ

So, 1/100 = 1/10²

= 10⁻²

Now, 2.543/100 = 2.543 × 10⁻²

Therefore, the required standard form is 2.543 × 10⁻² m.
