Gọi \(x\) là số học sinh giỏi lớp 5A. Theo đề bài ta có:
\(x\) x \(\dfrac{3}{5}\) = 6 ⇒ \(x\) = 6 x \(\dfrac{5}{3}\) = 10 (học sinh)
Vậy lớp 5A có 10 học sinh giỏi

Số học sinh lớp 5A là:
6 : \(\dfrac{3}{5}\)
= 10 ( em)
Đ/S: 10 em

Hi Mia,
thanks for the letter, that is a great idea to do this summer.... But I got another idea....
This summer I will make a project about the Planets in the space!! I love space, in the future I want to be an austronaut!! I will use the telescope to look for them and watch their move around us! and more more exciting things to do for my project!
great, isn't it?

Ta có:
\(x^3+x^2-4x=4\)
\(\Rightarrow x^3+x^2-4x-4=0\)
\(\Rightarrow\left(x^3+x^2\right)-\left(4x+4\right)=0\)
\(\Rightarrow x^2\left(x+1\right)-4\left(x+1\right)=0\)
\(\Rightarrow\left(x^2-4\right)\left(x+1\right)=0\)
\(\Rightarrow\left(x-2\right)\left(x+2\right)\left(x+1\right)=0\)
\(\Rightarrow x-2=0;x+2=0;x+1=0\)
\(\Rightarrow x\in\left\{2;-2;-1\right\}\)
