Question from karen, a student:

Q: Write the following in exponent from: a * a * a * a * * * a, where there are n -1 a's

note: *asterisk means times.


a × a = a2
a × a × a = a3
a × a × a × a = a4

What is the exponential form for a × a × a × a × a? What if there were 9 copies of a multiplied together? What if there were n-1 copies of a multiplied together?
