Question

so sánh

5²³ và 6. 5²²

72⁴⁵-72⁴⁴ và 72⁴⁴ -72⁴³

Answer 1

\(5^{23}\)=     \(5\cdot5^{22}\)<     \(6\cdot5^{22}\)

Answer 2

5²³ < 6.5²²

72⁴⁵ - 72⁴⁴ > 72⁴⁴ - 72⁴³

Answer 3

Giải:

5²³ < 6. 5²²

72⁴⁵-72^{44 =} 72⁴⁴ -72⁴³

Answer 4

phải giải thích nữa chứ

Answer 5

vì sao

Answer 6

\(72^{45}-72^{44}=72\cdot72^{44}-72^{44}=71\cdot72^{44}\);\(72^{44}-72^{43}=72\cdot72^{43}-72^{43}=71\cdot72^{43}\)

vì\(71\cdot72^{44}>71\cdot72^{43}\)nên\(72^{45}-72^{44}>72^{44}-72^{43}\)
