999 945 467 x 33 = 32 998 200 411 sai nha bn kết quả phải bằng 32998207011

sai nha b

\(A=1^5+2^5+3^5+......+100^5\)

Ta luôn có \(a^n+b^n=\left(a+b\right)\left(.....\right)\)   \(\text{∀}\) \(n\) ∈ \(N\) , \(n:\) \(lẻ\)

\(A=\left(1^5+99^5\right)+\left(2^5+98^5\right)+.....+\left(49^5+51^5\right)+100^5+50^5\)

\(A=\left(99+1\right)\left(...\right)+\left(2+98\right)\left(....\right)+....+\left(49+51\right)\left(....\right)+100^5+50^5\)

\(A=100\left(...\right)+\left(40+10\right)^5\)

\(Đặt\) \(P=\left(40+10\right)^5=40^5+10^5+5.40^4.10+10.40^3.10^2+10.40^2.10^3+5.40.10^4+10^5\)

Dễ thấy \(P\) ⋮ 4 \(=>A\) ⋮ 4 \(=>\) đpcm

Nam and Phong are best friend, but Minh is Phong neighbour. One day, three of them were in the garden that was very near to their house. Minh is a very shy and clever guy, so he was reading his book and sat on the grass while Nam and Phong were playing basketball. Both of them were a very successful . After a will, Phong threw the ball to Minh and invited him to join both of them. After Minh made up his mind, he joined them immediately. They taught him how to play basketball. And soon, they became best friends, and often plays basketball together.

Em cảm ơn nhiều ạ! Tick nèk :3

a)\(\dfrac{1}{Rtđ}=\dfrac{1}{R1}+\dfrac{1}{R2}=\dfrac{1}{8}+\dfrac{1}{12}=\dfrac{5}{24}\)

\(\Rightarrow Rtđ=\)4,8

b)ta có:U=U1+U2=I.Rtđ=3.4,8=14,4

c)I1=\(\dfrac{U1}{R1}=\dfrac{14,4}{8}\)=1,8

I2=I-I1=3-1,8=1,2

mik lộn chút U=U1=U2 nhé

Bạn chụp rõ nét đc ko ạ, mik đang ko có kính ở đây

dạ đây ạạ chị giải giúp em với 

a: Xét ΔBAM và ΔCAN có

BA=CA

\(\hat{BAM}=\hat{CAN}\)

AM=AN

Do đó: ΔBAM=ΔCAN
