Question

log x + log y equals to 7 then log root x ylog x + log Y = 27 then log root x y value

Answer 1

Answer:

Step-by-step explanation:

Ans x=1000, y=100

Equation 1

log x/log y = 3/2

2 log x = 3 log y

Equation 2

log(xy) = 5

logx +logy = 5

Using Equation 1 i.e log y = 2/3 log x in 2

3 log x + 2 log x = 15

Therefore log x=3

Using Log x value in equation 2

we get, log y=2

log x = 3, log y = 2

x = 10^3, y = 10^2
