Answer:
They are both right becuase if you just take away 1 from 20 and 10 you get 2 and 1. For the 4:2 one take away 1 and mutiply by 2 equalling 4:2 but they are still the same thing.

Hello!
In this problem, we will need to know our properties of exponents.
When we multiply two exponents, for example 10^3 × 10^-1, we will need to add the powers together. So, 10^3 × 10^-1 = 10^2 or 100.
With this, we can multiply the two constants together, and the exponents together to find our quotient.
(8.2 × 10^-6) × (9.4 × 10^-3) (rearrange the expression)
8.2 × 9.4 × 10^-6 × 10^-3 (multiply)
77.08 × 10^-9
If you wanted your answer to be in scientific notation, move the decimal place in 77.08 one place to the left, leaving you with 7.708 × 10^-8.
Therefore, your final answer is 7.708 × 10^-8.
