Lời giải:
a. $99^3+1+3(99^2+99)=99^3+3.99^2.1+3.99.1^2+1^3=(99+1)^3=100^3=1000000$
b. $11^3-1-3(11^2-11)=11^3-3.11^2.1+3.11.1^2-1^3=(11-1)^3=10^3=1000$
1 ơi + 2 ơi = 3 ơi chứ bằng mấy nữa bạn, kết bạn với mình nha
Hi my name is Linh and currently I’m 12 years of age. I have a nice personality and am very easy to get along with. This is my first semester of secondary school a lot of other people. What I to do in my spare time is to play video games and just relax with friends and family. People may see that as somewhat weird to play video games as a hobby, but it’s what I really to do. I prefer to enjoy things at my own space. This whole blogging thing is new to me and I really it. It could probably make me new friends and people that have common interests with me.
\(\left(2x-3\right)\cdot4,8=\left(3x+1\right)\cdot\left(-2,4\right)\)
\(9,6x-14,4=-7,2x-2,4\)
\(9,6x+7,2x=14,4-2,4\)
\(16,8x=12\)
\(x=\dfrac{12}{16,8}=\dfrac{5}{7}\)
1 + 1 =2
