Ответ:
Using the geometric mean concept, it is found that the value of a is 18.
----------------------
The geometric mean, of a data-set of n elements,
, is given by:
That is, the nth root of the multiplication of all elements.
----------------------
In this question:
Two elements(n = 2), a and 34.Thus:
We find the square of each side, so:
Simplifying both sides by 17:
The value of a is 18.
