उत्तर

Let I = `int ("e"^(6logx) - "e"^(5logx))/("e"^(4logx) - "e"^(3logx)) "d"x`

= `int ("e"^(log x^6) - "e"^(log x^5))/("e"^(logx^4) - "e"^(log x^3)) "d"x`  .....[∵ a log b – log ba]

= `int (x^6 - x^5)/(x^4 - x^3) "d"x`  .....[∵ elogx = x]

= `int (x^3 - x^2)/(x - 1) "d"x`

= `int (x^2(x - 1))/(x - 1) "d"x`

= `int x^2 "d"x`

= `x^3/3 + "C"`
