Exponential Notation is an easier way to write a number as a product of many factors. The exponent tells us how many times the base is used as a factor.
Now onto the actual problem.
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 only use whole intergers with exponents, then that would be the only way. If not you can do, 625 = 25*5<span>²
it would be 4m because there are four different copies and the variable being used originally is 'm'. therefore, we can move it around and since addition is basically the longer version of multiplication, we would correct this to 4m.
