Question

If a power x =b power y= ab, then find the value of y.

i) (x-1)/x ii) (x+1)/x iii) x/(x-1)

Answer 1

pls rewrite the first line with commas to separate things n make them clear

Answer 2

a^x=b^y=ab, then find "y" in terms of "x" as given in the options.

Answer 3

I have done like this. Plz say whether it is correct or not.

Given, a^x=ab
Or, a^(x-1)=b
Also, given that, b^y=ab
Substituting, we get, [a^(x-1)]^y=ab
Or, a^(xy-y)=a^x
Or, xy-y=x
Or, y(x-1)=x
Or, y = x/(x-1)
