Answer:
Step-by-step explanation:
Factor of 21= 7 and 3
So its exponential form will be (7*3)^1
Other exponential forms can be [(11)^2 -1]^1
21 is a composite number. Also it doesn't have so much multiples or common multiples.
Another form can be [(5)^2 - 1]
If the number would be like 22... then we could express it as perfect square.
