The general form for a term with fractional exponents is given as :
![a^{ \frac{m}{n} }](https://tex.z-dn.net/?f=a%5E%7B%20%5Cfrac%7Bm%7D%7Bn%7D%20%7D)
which can be rewritten as
![(\sqrt[n]{a} )^m](https://tex.z-dn.net/?f=%20%28%5Csqrt%5Bn%5D%7Ba%7D%20%29%5Em)
for example:
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![(r)^{n-1}](https://tex.z-dn.net/?f=%28r%29%5E%7Bn-1%7D)
where a is the first term and r the common ratio
Here a =
and r = 10 , thus
=
![(10)^{n-1}](https://tex.z-dn.net/?f=%2810%29%5E%7Bn-1%7D)
=
× ![10^{n-1}](https://tex.z-dn.net/?f=10%5E%7Bn-1%7D)
= 3 ×
× ![10^{n-1}](https://tex.z-dn.net/?f=10%5E%7Bn-1%7D)
= 3 × ![10^{n-3}](https://tex.z-dn.net/?f=10%5E%7Bn-3%7D)
Thus
= 3
→ C
