Question

X=(log75+log9+log5)÷(log5+log45)

Answer 1

Step-by-step explanation:

(Log75+log9+log5)÷(log5+log45)

= log(75*9*5) / log(5*45)

= log 3375 / log 225

= log(25*9*15) / log(25*9)

= log(5^2 * 3^2 * 15)/log(5^2 * 3^2)

= log( 15^2 * 15) / log (15^2)

= (log 15^2 + log 15)/ log 15^2

= (2log15 + log15)/(2log15)

= 3log15/(2log15)

= 3/2
