The third term of a G.P. is 4, the product of the first five terms is ______.
उत्तर
The third term of a G.P. is 4, the product of the first five terms is (4)5.
Explanation:
Given T3 = 4
∴ ar2 = 4 .....(i)
Product of first five terms = a · ar · ar2 · ar3 · ar4
= a5r10
= (ar2)5
= (4)5 ......[From equation (i)]
