Select all the equivalent to a^2/a^9 assume a doesnt equal 0

a ^ 2 / a ^ 9
 For this case what you should do is use the power properties to write the expression in different ways.
 Three different ways to write the expression are:
 Way 1:
 a ^ 2 / a ^ 9 = a ^ (2-9) = a ^ (- 7) = 1 / a ^ 7
 1 / a ^ 7
 Way 2:
 a ^ 2 / a ^ 9 = a ^ (2-9) = a ^ (- 7)
 a ^ (- 7)
 Way 3:
 a ^ 2 / a ^ 9 = a ^ 2 * a ^ (- 9)
 a ^ 2 * a ^ (- 9)
 
 all the equivalent to a ^ 2 / a ^ 9 are:
 1 / a ^ 7
 a ^ (- 7)
 a ^ 2 * a ^ (- 9)

Iwish i knew the answer but i don’t but someone will come and us
