Một số gồm 6 chữ số bắt đầu bằng chữ số 8. Số này chia hết cho 9 và tất cả các chữ số của số này đều khác nhau. Giá trị nhỏ nhất có thể có của số này là gì? MNPQ là hình vuông được tạo thành từ các hình chữ nhật giống hệt nhau và hai hình vuông có diện tích 9cm2 và 16cm2. Diện tích của hình vuông MNPQ là? Tôi có hai chữ số trong phần thập phân. Tôi lớn hơn 75 nhưng nhỏ hơn 80. Tôi ít nhất có thể là số nào?

The first side of the square known as a ; 2nd side of the square is b \(\left(a>b\right)\)
\(\Rightarrow a^2+b^2=100\)
\(\Rightarrow a^2+b^2=36+64\)
\(\Rightarrow\begin{cases}a=8\\b=4\end{cases}\)
