1. So sánh:

a) 2³⁰ và 3²⁰

Ta có :

2³⁰ = 2^3.10 = (2³)¹⁰ = 8¹⁰

3²⁰ = 3^2.10 = (3²)¹⁰ = 9¹⁰

Vì : 8¹⁰ < 9¹⁰

=> 2³⁰ < 3²⁰

b) 10²⁰ và 20¹⁰

Ta có :

10²⁰ = 10^2.10 = (10²)¹⁰ = 100¹⁰

Vì 100¹⁰ > 20¹⁰

=> 10²⁰ > 20¹⁰

My father tells us don't go out in the evening .

c) E = \(\dfrac{4116-14}{10290-35}\) và K = \(\dfrac{2929-101}{2.1919+404}\)

E = \(\dfrac{4116-14}{10290-35}\)

E = \(\dfrac{14.\left(294-1\right)}{35.\left(294-1\right)}\)

E = \(\dfrac{14}{35}\)

K = \(\dfrac{2929-101}{2.1919+404}\)

K = \(\dfrac{101.\left(29-1\right)}{101.\left(38+4\right)}\)

K = \(\dfrac{29-1}{34+8}\)

K = \(\dfrac{28}{42}\) = \(\dfrac{2}{3}\)

Ta có : E = \(\dfrac{14}{35}\) và K = \(\dfrac{2}{3}\)

\(\dfrac{14}{35}\) = \(\dfrac{42}{105}\)

\(\dfrac{2}{3}\) = \(\dfrac{70}{105}\)

Vậy E < K
