The usual form for 2 × 10⁻² is not equal to 0.02. State whether the statement is true or false.

Solution:

Given, the usual form for 2 × 10⁻² is not equal to 0.02.

Using law of exponents,

a⁻ⁿ = 1/aⁿ

So, 10⁻² = 1/10²

= 1/100

Now, 2 × 10⁻² = 2 × 1/100

= 2/100

= 0.02

Therefore, 2 × 10⁻² is equal to 0.02.
