Answer 1

a)2log((x-y)/2)=logx+logy+log2

2log((x-y)/2)=log(2xy)

log(((x-y)/2)^2)=log2xy

(x-y/2)^2=2xy

x^2+y^2-2xy=8xy

x^2+y^2=10xy

(x^2+y^2)/xy=10

x/y+y/x=10

b) 3log(x+y)=3logx+3logy+3log2

log(x+y)^3=log(2xy)^3

x+y=2xy

1/x+1/y=2

c) log(75/16)-2log5/9+log(32/243)=logp

log(75/16)-log(25/81)+log(32/243)=logp

log(75/16×32/243÷(25/81))=logp

p=2
