Given data:
The expression of the first option is,
Thus, the above expression are not equivalent.
The expression in the second option is,
Thus, yes they are equivalent.
The expression in the third option is,
Thus, the above expression are not equivalent.
The expression in fourth option is,
Thus, yes the above expression is equivalent.
Answer:
C
Step-by-step explanation:
There is a common ratio between consecutive term in the sequence, that is
÷
= 3 ÷
= 30 ÷ 3 = 300 ÷ 30 = 10
This indicates the sequence is geometric with n th term
= a
where a is the first term and r the common ratio
Here a = and r = 10 , thus
=
= ×
= 3 × ×
= 3 ×
Thus
= 3
→ C
