sau khi chuyển thì đơn vị 1 có số người là:

             (70+6):2=38(người)

sau khi chuyển thì đơn vị 2 có số người là:

             70-38=32(người)

vì 2 đơn vị có số người bằng nhau nên lúc đầu mỗi đơn vị có 35 số người .

vậy mỗi đơn vị có 35 người.

Lớp 8 thì đăng vào phần lớp 8 ấy.

a) Ta có: \(2x^2y\cdot\left(-2.5x^3y^2z\right)\)

\(=\left(-2.5\cdot2\right)\cdot\left(x^2\cdot x^3\right)\cdot\left(y\cdot y^3\right)\cdot z\)

\(=-5x^5y^4z\)

a) Ta có: \(12x^5y^2\cdot\left(-12.5zx^2y^5z\right)\)

\(=\left(-12.5\cdot12\right)\cdot\left(x^5\cdot x^2\right)\cdot\left(y^2\cdot y^5\right)\cdot z^2\)

\(=-150x^7y^7z^2\)
