Answer 1

`\\ \tt\hookrightarrow log_45+2log_43-log_415=x`

`\boxed{\sf log_ab=bloga}`

`\\ \tt\hookrightarrow log_45+log_43^2-log415=x`

`\\ \tt\hookrightarrow log_45+log49-log415=x`

`\boxed{\sf log_abc=log_ab+log_ac}`

`\\ \tt\hookrightarrow log_4(5)(9)-log_415=x`

`\\ \tt\hookrightarrow log_445-log_415=x`

`\boxed{\sf log_a(b/c)=log_ab-log_ac}`

`\\ \tt\hookrightarrow log_4\left((45)/(15)\right)=x`

`\\ \tt\hookrightarrow log_43=x`

`\\ \tt\hookrightarrow 3log4=x`

`\\ \tt\hookrightarrow x=3(0.602)`

`\\ \tt\hookrightarrow x=1.806`
