Question

log{1/3(a+b)} = 1/2(log a + log b)
then a^2 + b^2 = ?

Answer 1

any1 answer

Answer 2

how ?

Answer 3

u want options :
a) 9ab
b) 7ab
c) 5ab
d) none of these

Answer 4

loga+logb=logab
1/2log(ab)=logab^1/2
now (ab)^1/2=1/3(a+b)
a+b=3(ab)^1/2
(a+b)^2=9ab
a^2+b^2=(a+b)^2 - 2ab

hence 9ab -2ab =7ab
