\(44^{55}=\left(44^5\right)^{11}=\left(4^5.11^5\right)^{11}\)

\(55^{44}=\left(55^4\right)^{11}=\left(5^4.11^4\right)^{11}\)

mà \(11^5>11^4\) và \(4^5>5^4\)

=>\(\left(4^5.11^5\right)^{11}>\left(5^4.11^4\right)^{11}\)

=>\(44^{55}>55^{44}\)

44^55<55⁴⁴

nhớ k cho mình nha

Mình làm luôn nhé !

TL :

 = (55⁴)¹¹ và (44⁵)¹¹

 = 220¹¹ và 220¹¹

= 220¹¹ = 220¹¹

=> 55⁴⁴ = 44⁵⁵

Ta có : \(55^{44}=\left(55^4\right)^{11}=9150625^{11}\)

            \(44^{55}=\left(44^5\right)^{11}=164916224^{11}\)

\(9150625^{11}< 164916224^{11}\text{ }\Rightarrow\text{ }55^{44}< 44^{55}\)

\(A=\frac{54\times17-44}{54\times16+10}\)

\(=\frac{54\times16+54-44}{54\times16+10}\)

\(=\frac{54\times16+10}{54\times16+10}=1\)

\(B=\frac{55\times19-45}{55\times18+9}=\frac{55\times18+55-45}{55\times18+9}\)

\(=\frac{55\times18+9+1}{55\times18+9}=1+\frac{1}{55\times18+9}>1\)

=>B>A

22 + 33 = 55 

Duyệt mình nha

22 + 33 = 55

11 + 11 = 22

22 + 22 = 44

33 + 33 = 66

44 + 44 = 88

55 + 55 = 110

Học tốt~

11+11=22

22+22=44

33+33=66

44+44=88

55+55=110
