Division Properties of Exponents

What is the simplified form of each expression?

1. n^6/n2
a- 1/n^4
b- n^4
c- n^8
d- n12

( I figured I would start this since nobody need help for this unit apparently ) ( Unit 3, Lesson 6 for FVCA )

The simplified form of n^6/n^2 is n^4. Therefore, the answer is b.
