Question

(1.8 x 10^-2) = (9 x 10^2) =
2 x 10-5
2.0 x 10-5
O 0.2 x 10-4

Answer 1

Answer: The answer is 2.0 x 10^-5

Explanation: Just did this :)

Answer 2

0.2 x 10⁻⁴

Step-by-step explanation:

The problem here is to evaluate:

(1.8 x 10⁻²) ÷ (9 x 10²)

To solve this problem, some certain rules of indices must be followed. In the event that we have an expression such as:

(a x bˣ ) ÷ (c x bᵃ) =
`(a)/(c)` x bˣ⁻ᵃ

So;

(1.8 x 10⁻²) ÷ (9 x 10²) =
`(1.8)/(9)` x 10⁻²⁻²

= 0.2 x 10⁻⁴
