Answer:
3
Step-by-step explanation:
<em>This is cube root (hence the </em>).
To find the cube root of a number, we are looking for a number that, when multiplied by itself 3 times, equals the number inside the sign.
So:
We know that , so this doesn't work.
We also know that , so this works.
Therefore the cube root of 27 is 3.
Hope this helped!
Answer:
Option (1)
Step-by-step explanation:
In a geometric series,
Here r =
For |r| < 1, series will converge.
For |r| > 1, series will diverge.
Option (1)
Given geometric series is,
Common ratio =
=
Since,
Series will converge.
Option (2)
r =
Since, 2 > 1,
Series will diverge.
Option (3)
Common ratio 'r' =
Since, 3 > 1,
Series will diverge.
Option (4)
Common ratio 'r' =
Since, 6 > 1
Series will diverge.
Therefore, Option (1) will be the correct option.
