PLEASEEEEEEEE HELP!!! I DO NOT UNDERSTAND!

Answer:
81
Step-by-step explanation:
If a = 4, the exponent will be [tex]3^{4}[/tex].
[tex]3^{4}[/tex] represents 3 being multiplied by itself 4 times.
[tex]3^{4}[/tex] = 3·3·3·3
[tex]3^{4}[/tex]=9·3·3
[tex]3^{4}[/tex]=27·3
[tex]3^{4}[/tex]=81
Your product is 81.
