well, we can say that √2 and √7 are irrational numbers, they do not provide a value that can be written in a "ration" or fractional.
we can also say that √2 * √7 is √(14), which is also irrational.
However, how about √7 * √7, that's √7² or namely just 7, and that's a rational, so nope, not always.
Answer:
13.
π
14.
π
15. 
Step-by-step explanation:
13.
A = π * 
r =
A = π* 
A = π * 
A = π * 
A =
π

V = π *
* h
r = 
h = 
V = π *
* 
V = π *
* 
V = π * 
V =

The explicit formula for the geometric sequence
is

Step-by-step explanation:
The formula of the nth term of a geometric sequence is
, where:
- a is the first term of the sequence
- r is the common ratio between the consecutive terms
The geometric sequence of
is 6 , -2 ,
,
, 
∵
= 6
∵ 
∵
= -2
∴ 
- Divide both term by 2 to simplify it
∴ 
∵ 
- Substitute the value of
and r in the rule above
∴ 
The explicit formula for the geometric sequence
is
