Find the geometric mean between
(i) 6 and 24 (ii) -9 and -25 (iii) -6 and 9

Text Solution

Verified by Experts

(i) The GM between 6 and `24=sqrt(6xx24)=sqrt(144)=12`.
(ii) The GM between -9 and `-25 =sqrt((-9)xx(-25))=sqrt(225)=-15`.
(iii) Since the GM between two numbers of opposite signs does not exist, so the GM between -6 and 9 does not exist.
