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)
Answer:
Option C and D!
Step-by-step explanation:
When 9 is placed in the box after 7, we get:-
7 ÷ 9 = 
which is correct!
<u>7 ÷ 9 can also be written as </u><u>. So, this Option is right since the equation is correct when 9 is placed in the box!</u>
- Option D is also correct because,
When we place 9 in the box before 
, we get:-
9 ÷ = 81
9 ÷ equals 9 x 9 (take the reciprocal of )
<u>9 x 9 equals 81 which means the equation is correct when 9 is placed in the box!</u>
