6. 
   misol. x⁶ = 6^x tenglamaning ildizlarini Maple matematik paket yordamida ajrating.
   

Yechish. Bu tenglamani f(x) = x⁶/6^x – 1 = 0 ko‘rinishda yozib, f(x) ning grafigini [–1;7] kesma uchun Maple matematik paket yordamida chi- zamiz:

Rasmdan ko‘rinadiki, berilgan tenglama uchta haqiqiy ildizga ega: – 0,789877; 1,62424; 6. Bu ildizlarni ajratish, ularni taqribiy hisoblashni mustaqil bajaring.
