Question

So sánh:

a)2³³³  và 3²²²

b)99²⁰ và 9999¹⁰

Answer 1

2³³³=(2³)¹¹¹=8¹¹¹

3²²²=(3²)¹¹¹=9¹¹¹

Vì: 8<9 nên: 8¹¹¹<9¹¹¹

vậy: 2³³³<3²²²

b, 99²⁰=(99²)¹⁰=9801¹⁰

Mà: 9801<9999 nên:

99²⁰<9999¹⁰

Answer 2

aTa có:

2³³³=(2³)¹¹¹=8¹¹¹

3²²²=(3²)¹¹¹=9¹¹¹

Do 8¹¹¹<9¹¹¹

=>2³³³<3²²²

b,Ta có:

99²⁰=(99²)¹⁰=9801¹⁰

Do 9801¹⁰ <9999¹⁰

=>99²⁰<9999¹⁰
