Answer:


1.5*10^(-18)

Explanation:

The question is in the format
(8.4*10^9)/(n)=5.6*10^(27)

First multiply both sides by n and then divide both sides by the number in scientific notation on the right.


(8.4*10^9)/(5.6*10^(27))=n

We can think of this problem as
(8.4)/(5.6)*(10^(9))/(10^(27))=(8.4)/(5.6)*10^9*10^(-27)

When dividing like-terms, we subtract their powers (or we can get the multiplicative inverse and add the powers).

We end up with
1.5*10^(-18)

Answer:

1.5x10^-18

Explanation:

8.4x10^9 / x = 5.6x10^27

You could make a proportion:

x(5.6 x 10^27)= 8.4x10^9

divide both sides by 5.6x10^27

x=1.5x10^-18
