Question

If a* = bx = c* and b2 = ac.
2xz
Prove that y = -
x+Z​

Answer 1

Answer:

Stlet us take a^x=b^y=c^z=k

then a=k^1/x, b=k^1/y, c=k^1/z

.Given, b²=ac.

substitute in the value of A B and C that we got

.then you will get

k^2/y=k^(1/x+1/y)

base is same. so we can equate powers

.we get 2/y=1/x+1/y=(x+y)/xy.so y is 2xy/x+y.
