Question

Express in terms of log 2 and log 3 :
`"log"26/51 - "log"91/119`

Sum

Solution

`"log"26/51 - "log"91/119`

= `"log"((26/51)/(91/119))   ....[ log_am - log_an = log_a(m/n)]`

= `"log"26/51 xx 119/91`

= `"log" [ 2 xx 13 ]/[ 3 xx 17 ] xx [ 7 xx 17 ] /[ 7 xx 13 ]`

= `"log" 2/3`
= log 2 - log 3      ......[ loga`m/n` = logam - logan ]
