mik nghĩ là 5 = 1

học tốt

kb nhé, vì 1 = 5 rồi thì, 5 = 1 chứ bằng mấy nữa

Chị nghĩ là bằng 25.Nếu đúng nhớ k cho chị nha.

5=25 + thêm 5

33/66=1/2

7878/5757=26/19 nha

~HT~

K cho mình nha 

@@@@@@@@@@@@@@@@@

\(\frac{33}{66}=\frac{33:33}{66:33}=\frac{1}{2}\)

\(\frac{7878}{5757}=\frac{7878:101}{5757:101}=\frac{78}{57}\)

/HT\

\(\frac{33}{66}\)\(=\frac{33:33}{66:33}\)\(=\frac{1}{2}\)

\(\frac{7878}{5757}\)\(=\frac{7878:101}{5757:101}\)\(=\frac{78}{57}\)\(=\frac{26}{19}\)

\(1.8.9.5.7.4.7.4.7.9=17781120\)

\(1.8.9.5.7.4.7.4.7.9\)

\(=\left(1.8.9.5.7\right).\left(4.7.4.7.9\right)\)

\(=2520.7056\)

\(=\text{17781120}\)

a) A = 1 + 3 + 3² + ... + 3⁷ 

3A = 3 ( 1 + 3 + 3² + .. + 3⁷)

3A = 3 + 3² + 3³ + ...+ 3⁸

b) Vì 3A = 3 + 3² + 3³ + ...+3⁸

2A = 3⁸- 1

A = ( 3⁸-1) : 2 (Điều phải chứng minh)

a) A = 1 + 3 + 32 + ... + 37 

3A = 3 ( 1 + 3 + 32 + .. + 37)

3A = 3 + 32 + 33 + ...+ 38

b) Vì 3A = 3 + 32 + 33 + ...+38

2A = 38- 1

A = ( 38-1) : 2 (Điều phải chứng minh)

Mong bạn tick cho mình
