(ii)If the third term of G.P.is 4, then ...

(ii)If the third term of G.P.is `4`, then find the product of first five terms

A

`4^(3)`

B

`4^(4)`

C

`4^(5)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
It is given that `T_(3)=4`
let and r the term and common ratio respectively
then `ar^(2)=4`
Product of first 5 terms `=a.ar .ar^(2).ar^(3).ar^(4)`***(i)
`a^(5) r^(10)=(ar^(2))^(5)=(4)^(5)` [using Eq ,(i) ]
