Question

Calculate 8 ∙ 10-4 divided by 2 ∙ 102.

Answer 1

8 * 10 - 4
= 80 - 4
= 76

2 * 102 = 204

76/204 = 19/51

Hope this helps!

Answer 2

Explanation :

Here,
`8* 10^(-4)` is numerator and
`2* 10^(2)` is the denominator.

Two numbers are given i.e.

`n_1=8* 10^(-4)`

`n_2=2* 10^(2)`

We have to divide these two numbers.

`(n_1)/(n_2)=(8* 10^(-4))/(2* 10^(2))`

`4* 10^(-6)`

Hence, this is the required solution.
