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)

<h3>Given :</h3>
- Distance = 175
- Time 1 = 4 hours
<h3>To find:</h3>
- Different between two speeds when distance is same.
<h3>Solution:</h3>
<u>Part</u><u> </u><u>1</u><u> </u><u>:</u>
In first part we will find speed 1 in which time is 4 hours
we know:-
So:-
<u>Part 2</u>
In first part we will find speed 2 in which time is 3 hours
Again:
<u>Part 3</u>
In this part we will find different between speed 1 and speed 2
So :
Answer:
6973568802
Step-by-step explanation:
I memorized the equation: A(n) = A(1)*d^(n-1).
You can plug into the equation A(21) = 2*3^20, which can be solved to 6973568802. (I solved this step through a calculator by finding 3^20, then multiplying that by 2 to get 6973568802.
Hope this helps!
Answer:
5.5
Step-by-step explanation:
4(x+2)=30
4x+8=30
4x=30-8
4x=22
x=22/4
x=5.5
