Answer:
[tex]a.\ 9= 3^2\\\\b.\ 27 =3^3\\\\c.\ 81= 3^4\\\\d. 243= 3^5[/tex]
Step-by-step explanation:
It is important to remember the that Exponential notation is in the form:
[tex]b^n[/tex]
Where:
Therefore, given the numbers [tex]9,27,81\ and\ 243[/tex], you need to descompose them into their prime factors and then you must write them in exponential notation using 3 as the base.
Then:
[tex]a.\ 9=3*3= 3^2\\\\b.\ 27 = 3*3*3=3^3\\\\c.\ 81 = 3*3*3*3 = 3^4\\\\d. 243 =3*3*3*3*3= 3^5[/tex]
