Step-by-step explanation:
We want to simplify
We expand the parenthesis to get;
We group similar terms to get:
Combine the terms;
Therefore the simplified expression in standard form is:

First, you can factor out 625 using the 'tree' method or the 'ladder' method.
625
/ \
5 125
/ \
5 25
/ \
5 5
This means you can say that 625=5 to the power of 4
If your problem requires you to use only whole integers with exponents, then that would be the only way.
If not, then you can also do 625=25*5²
No she is not right.
Dividing blocks by minutes would be 12/36 = 1/3
The ratio would be 1:3 meaning she runs 1 block every 3 minutes.
