Question

Find H.M. of two positive numbers A.M. and G.M. are 15/2 and 6 respectively​

Answer 1

Answer:

Answer:

a+b\2=15\2

a+b=15

√ab=6

ab=36

so a=12 b=3

Answer 2

Step-by-step explanation:

let x and y be positive numbers

GM= √xy

AM =(x+y)/2

HM =2xy/(x+y)

AM(HM)=xy =GM^2

now

GM^2 =(AM)(HM)

=12(3)=36=6^2

GM =6
