Question

log x + y by 3 equal to 1 by 2 log x + logy find X by Y + y by x​

Answer 1

Step-by-step explanation:

logx+y÷3=1÷2 logx+logy

2logx+y÷3=log x+logy

log(x+y÷3)square= log xy

logx2+y2+2xy÷9=log xy

logx2+y2+2xy=log9xy

x2+y2=9xy-2xy

x2+y2=7xy

then,

x÷y+y÷x= 7

Answer 2

Answer:

logx+y÷3=1÷2 logx+logy

2logx+y÷3=log x+logy

log(x+y÷3)square= log xy

logx2+y2+2xy÷9=log xy

logx2+y2+2xy=log9xy

x2+y2=9xy-2xy

x2+y2=7xy

then,

x÷y+y÷x= 7
