4. rewrite each number in exponential notation using 3 as the base.
a. 9 = 3 x 3 = 32
b. 27 = 3 x 3x3 = 33
c. 81 = 3x3x3x3 = 34
d. 243 = 3x3x3x3x3 = 35
i need asap

Step-by-step explanation:

It is important to remember the that Exponential notation is in the form:

Where:

Therefore, given the numbers , you need to descompose them into their prime factors and then you must write them in exponential notation using 3 as the base.

Then:
