Answer:
3 x 3 x 3 x 3 x 3 x 3 x 3 = 2,187
(or 3 x 7 = 2,187)
2,187 x 9 = 19,683
Step-by-step explanation:
The little seven next to the three is a exponent, that means there is the amount of threes as the exponent. Find out what 3 x 7 is. You should have gotten 2,187. Then multiply that answer that you got with the number you are multiplying with (9). You should get your answer 19,683.
Hope this helped you understand :)
You just have to put the term number back into your nth term.
15×3=45
45-7= 38
The 15th term of 3n-7 = 38
Hope this helps!
Given:
The equation is
To find:
The inverse operation for the equation using the knowledge of inverse operations.
Solution:
We have,
Here, 4560 is divided by 120. So, in this equation the operation is division.
We know that inverse operation of division is multiplication. So, multiply both sides by 120.
It can be written as
The inverse operation for the equation is .
Therefore, the correct option is B.
