Answer 1

Ta có: \(72^{45}-72^{44}=72^{44}\left(72-1\right)\)

          \(72^{44}-72^{43}=72^{43}\left(72-1\right)\)

=> \(72^{44}\left(72-1\right)>72^{43}\left(72-1\right)\) hay \(72^{45}-72^{44}>72^{44}-72^{43}\)

Answer 6

Ta có :

72⁴⁵ - 72⁴⁴ = 72⁴⁴ ( 72 - 1 )

72⁴⁴ - 72⁴³ = 72⁴³ ( 72 - 1 )

=> 72⁴⁴ ( 72 - 1 ) > 72⁴³ ( 72 - 1 )

Hay 72⁴⁵ - 72⁴⁴ > 72⁴⁴ - 72⁴³
