Answer: FIRST OPTION.
Step-by-step explanation:
For this exercise it is important to remember a property called "Quotient of Powers property".
By definition the Quotient of Powers property states the following:

You can observe the division of
and
. Since both have the same base "a" , you must rewrite the base and subtract the exponents "m" and "n".
In this case, you have the following expression given in the exercise:

Then, you need to apply the Quotient of Powers property rewriting the base 4 and subtracting the exponents 12 and 5.
Therefore, you get the following result:

You can notice that it matches with the first option.
Answer:
There are many possible answers since 5 is already greater than 3.

Answer:
r=20
Step-by-step explanation:
take the number you have, divide it by the numerator, and multiply it by the denominator, like shown:
4/5 of a number (r) is 16
16/4=4
4*5=20
r=20
ta-da! :P
