How do you calculate # (4 times 10 ^-3 )/(8 times 10^-7)#?
As the question's format is of a particular style we should write our answer in the same format (scientific notation).
But written in scientific notation we need 5.0 and not 0.5
so we write
Putting it all together we have:
See the entire solution process below:
First, rewrite this expression as:
Now, use this rule of exponents to simplify the 10s terms:
