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)
Answer:
all the equivalent to a ^ 2 / a ^ 9 are:
1 / a ^ 7
a ^ (- 7)
a ^ 2 * a ^ (- 9)
