/(2x + y)
3^x = 5^y = 75^z
Take log,
x log3 = y log5 = z log75 = k
log 3 = k/x 5 = k/y
z = k/(log 25 ×3)
z = k/(2 log5 + log3)
z = k/{2(k/y) + (k/x)}
z = xy/(2x + y)

- If , then find the relation between x, y and z.
Given,
Therefore,
Again,
Comparing base, we get,
This is the relationship between x, y and z, i.e.,
