Natural ko`rsatkichli darajaning xossalari

Namangan viloyati Chortoq tumani 53-DIUM matematika va informatika fani o’qituvchisi Tursunova Nafisaning “Natural ko’rsatkichli daraja va uning xossalari mavzusida tayyorlagan taqdimoti

Natural ko`rsatkichli darajaning xossalari:

• 1-xossa: am ∙ an =am+n .
• 2-xossa: am: an =am-n , m>n , a≠0.
• 3-xossa: (am)n =amn .
• 4-xossa: (ab)n =an bn
• 5-xossa:

Yodda saqlang!

1. Quyidagilarni 2 ning darajasi ko`rinishida ifodalang:

2. Quyidagilarni 3 ning darajasi ko`rinishida ifodalang:

4.Javobi X16 ga teng bo`lgan misollarni toping.

Hisoblang:

Yechish:

= 1

Sonlardan qaysi biri katta : 544 mi yoki 2112 ?

Yechish: (213)4 > 544

544 < 2112

Hisoblang :

Yechish:

“Domino” o`yini

1.Ifodaning qiymatini toping :

Yechish:

Mustaqil foydalanish uchun ma’lumotlar

3.Taqqoslang:

Yechish:

bundan ,

4. Ifodani daraja shaklida yozing:

Yechish:

Ifodani daraja shaklida yozing:

Yechish:

10020 kattami yoki 900010

Yechish: 10020= (102)20 =1040 ;

9000= 9∙1000 = 9∙103 < 10∙103 =104 ;

900010<(104)10=1040 .

Demak, 10020 >900010

raxmat!
