Question

Explain how the Quotient of Powers Property was used to simplify this expression. 5 to the fourth power, over 25 = 52

Answer 1

5^4/25 = 52
The quotient law states that x^m divided by x^n = x^m-n, so I think ;

We first change 25 to 5^ 2
Therefore,
5^4/5^2 = 52

5^4-2 =52

5^2 = 52

Then we change the sum to logarithmic form, which is b^x=y is the same as log (base) b (y)= x

So,
Log (base) 5 (52)= 2

Use the calculator to find the value of the log on your left and the answer is:

2.45504.... = 2

Therefore 2 (to the nearest whole number) = 2
