1+4=5

2+5=5+7=12

3+6=9+12=21

8+11=19+21=40

đs 40

dễ ẹt chẳng khó 1 chút nào cả

1+4=5

2+5=7

3+6=8

8+11=19

=19 đúng ko

\(1\dfrac{2}{3}=\dfrac{5}{3}\)

số lớn là:

154:(5-3) x 5 =385

số bé là:

385 - 154 = 231

\(1\dfrac{2}{3}\) = \(\dfrac{5}{3}\)

Số thứ nhất là:

 154 : (5 - 3) x 5 = 385

Số thứ hai là:

  385 - 154 = 231

 

Ai trả lời được thì like cho mình để mình cho thêm nhiều câu hỏi toán hay hơn nữa nha.

P/s : T đei là ARMY

Trả lời :

BTS 7 - 1 = 7 ( vì sao thì các ARMY pk tự hỉu )

BTS 7 + 1 = 7 ( Ý nghĩa giống vs câu trên=> Tự hỉu )

~ Thiên_Mã ~

Trả lời : Mk ko là fan cx ko là Anti , cho mk trả lời nha :

BTS 7-1=0 ( Bởi vì trừ 1 người ra thì nhóm sẽ tan rã )

BTS 7+1=7 ( Bởi vì có ai xem vào thì BTS vẫn là BTS )

I am sitting here in the boring room

I am hanging around

I am waiting for you

I am driving around my car

I am driving too fast

I am driving too far

I am turning my head up and down

I am sitting here

I'm sitting here in a boring room
It's just another rainy Sunday afternoon
I'm wasting my time I got nothing to do
I'm hanging around I'm waiting for you
But nothing ever happens
And I wonderI'm driving around in my car
I'm driving too fast, I'm driving too far
I'd like to change my point of view
I feel so lonely, I'm waiting for you
But nothing ever happens
And I wonderI wonder how, I wonder why
Yesterday you told me 'bout the
Blue, blue sky
And all that I can see
Is just a yellow lemon tree
I'm turning my head up and down
I'm turning, turning, turning, turning
Turning around
And all that I can see
Is just another lemon treeSing dah
Dah-dah-dah-dam, dee-dab-dah
Dah-dah-dah-dam, dee-dab-dah
Dab-deedly dahI'm sitting here, I miss the power
I'd like to go out, taking a shower
But there's a heavy cloud inside my head
I feel so tired, put myself into bed
Well, nothing ever happens
And I wonderIsolation is not good for me
Isolation, I don't want to
Sit on a lemon tree
I'm steppin' around in a desert of joy
Maybe anyhow I'll get another toy
And everything will happen
And you wonderI wonder how, I wonder why
Yesterday you told me 'bout the
Blue, blue sky
And all that I can see
Is just another yellow lemon tree
I'm turning my head up and down
I'm turning, turning, turning, turning
Turning around
And all that I can see
Is just a yellow lemon tree
And I wonder, wonderI wonder how, I wonder why
Yesterday you told me 'bout the
Blue, blue sky
And all that I can see
And all that I can see
And all that I can see
Is just a yellow lemon tree

cái này khó tui chết liền:

a, A=\(\frac{n\left(n+1\right)}{2}\)

b,B=\(n^2\)

c, C=\(\frac{\left(n+1\right)\left(n+2\right)}{2}\)

Số tiền Mẹ mua củ tỏi là:

5×10000=50000(đồng)

Số tiền Mẹ mua củ hành là:

2×20000=40000(đồng)

 

1+1=2 

h2+o2=4

1 + 1 = 2.

h2 + 02 = h20.

1:1=1

1+1=2

x = { -19 , -18 , -17 , -16 , - 15 , ...... , 20 }

Tổng = 20

\(\text{ 1) - 20 ≤ x ≤ 21}\)

\(x=\left\{-19;-18;-17;....;19;20\right\}\)

Tổng các số nguyên x là :

\(=\left(-19\right)+\left(-18\right)+\left(-17\right)+...+19+20\)

\(\text{= 20 + [(-19) + 19] + [(-18) + 18] + ... + [(-1) + 1] + 0}\)

\(=20+0+0+.......+0+0\)

\(=20\)
