The values of mm and nn are not determined by the values of aa and bb.

Explanation:

We are given:

(m+n)/2 = sqrt(ab) = (ma+nb)/(m+n)m+n2=ab=ma+nbm+n

We want to find mm and nn in terms of aa and bb, but note that if a=ba=b and a > 0a>0 then:

(ma+nb)/(m+n) = (ma+na)/(m+n) = a = sqrt(a^2)ma+nbm+n=ma+nam+n=a=a2

and:

m+n = 2sqrt(a^2) = 2am+n=2a2=2a

There is no more information we have about mm and nn except that m+n = 2am+n=2a

So it is not possible to determine the value of mm or nn in terms of aa and bb.
