The paper clip below has the indicated length. What is the length in standard form.

Solution:

Given, the figure shows the paper clips.

The length of the clip is 0.05 m.

We have to write the length in standard form.

Any number can be expressed as decimal numbers between 1 and 10 multiplied by a power of 10. This form of representation is termed as the standard form.

0.05 = 5/100

= 5/10²

Using law of exponents,

a⁻ⁿ = 1/aⁿ

1/10² = 10⁻²

So, 5/10² = 5 × 10⁻² m

Therefore, the required length is 5 × 10⁻² m.
