Answer:
So we need to express [tex]6.25 * 10^{-5}[/tex].
What is being used here is scientific notation, and when the exponent is negative, that means the number is less than 1.
As the exponent is -5, we have to move the coma 5 positions to the left (if it was positive we would have done that put to the right), so:
[tex]6.25 * 10^{-5}=0.0000625[/tex]
If you don't understand what does it mean to move the coma to the left, see this example to understand it:
We move it one time from 6.25 --> 0.625
We move it two times from 6.25 --> 0.0625
We move it three times from 6.25 --> 0.00625
We move it four time from 6.25 --> 0.000625
What we are doing is adding 0 to the left and if the exponent was positive, we would add 0 to teh right.
So now we know that [tex]\boxed{6.25 * 10^{-5}=0.0000625}[/tex]
