✔ 最佳答案

(6+ log x3) / log( 100x )
= (6+ 3log x) / (log100 + logx)
= 3(2+ log x) / (2 + logx)
= 3

(6+ log x3) / log( 100x )

= (6+ 3log x) / (log100 + logx)

= 3(2+ log x) / (2 + logx)

= 3

.......
=6+3logx/(log100 +logx)
=6+3logx/(2+logx)

=6(2+logx)/(2+logx)+3logx/(2+logx)
=(12+6logx+3logx)/(2+logx)
=(12+9logx)/(2+logx)

6+ log x^3 / log( 100x )
=(6+ 3 log x)/ (log100 +log x)
=(6+ 3 log x)/(3+ log x)
