Question

8.4m^9n^5 divided by 2.1m^3n^5

Answer 1

Answer:
`4m^(6)`

Explanation:

`(8.4m^(9) n^(5) )/(2.1m^(3)n^(5))`

Dividing exponents is the same as subtracting the exponents, so

`(m^(9))/(m^(3)) =m^(9-3)=m^(6)`

`(n^(5))/(n^(5)) =n^(5-5)=n^(0)=1`

So now our equation looks like

`(8.4m^(6))/(2.1)`

Now we can divide the numbers

8.4/2.1 = 4

So your final answer is
`4m^(6)`
