Bạn ơi, điều mình muốn nói đầu tiên là bài của bạn chụp nghiêng quá, mình khá là khó đọc. Hiện tại, phần bạn gửi là kiến thức về Present Simple (Hiện tại đơn) về cách dùng và dấu hiệu nhận biết.

- Mấy phần bạn ghi ví dụ như là "Dùng để ..." là cách dùng của Hiện tại đơn.

- Còn phần "Dấu hiệu nhận biết" là cách để bạn chọn đúng thì khi làm bài.

Bạn có câu hỏi gì nữa không? Mình vẫn luôn ở đây để giúp bạn!

E cần giúp gì nhỉ

\(4^{2x+1}=1024\)

\(\Rightarrow4^{2x+1}=4^5\)

⇒ 2x + 1 = 5

2x = 5 - 1

2x = 4

x = 4 : 2

x = 2

Vậy x = 2

\(4^{2x+1}\) = 1024

(2\(^2\))\(^{2x+1}\) = \(2^{10}\)

\(2^{4x+2}\) = 2\(^{10}\)

4\(x+2\) = 10

4\(x\) = 10 - 2

4\(x\) = 8

\(x\) = 8 : 4

\(x=2\)

Vậy \(x=2\)

\(4^{2x+1}=1024\)

(2\(^2\))\(^{2x+1}\) = 2\(^{10}\)

\(2^{4x+2}\) = 2\(^{10}\)

\(4x+2\) = 10

4\(x\) = 10 - 2

4\(x\) = 8

\(x\) = 8 : 4

\(x=2\)

Vậy \(x=2\)

42x+1 = 1024

\(4^{2 x + 1}\) = \(4^{5}\)

=> 2x + 1 = 5

=> 2x = 5 - 1

=> 2x = 4

=> x = 4 : 2

=> x = 2

Vậy x = 2

Chúc bạn học tốt!

vâng ạ

13,24 + 100 - 3,24 - 2 x 50

= (13,24 - 3,24) + (100 - 2 x 50)

= 10 + (100 - 100)

= 10 + 0

= 10

13,24 + 100 - 3,24 - 2 . 50

= (13,24 - 3,24) + (100 - 2 . 50)

= 10 + (100 - 100)

= 10 + 0

= 10

41 sai đề

\(\rArr\) \(x-5=0\) hoặc \(2x-12=0\)

+) Với \(x-5=0\) \(\rArr x=5\)

+) Với \(2x-12=0\)

\(2x=12\)

\(x=6\)

Vậy x = 6 hoặc x = 5

x = 6 hoặc x = 5
