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.
a) 5 ; x+y ;2xy đồng dạng với 4xy ;a (x) = 25x + 2x2
b) -2xy
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: \(12x^5y^2\cdot\left(-12.5zx^2y^5z\right)\)
\(=\left(-12.5\cdot12\right)\cdot\left(x^5\cdot x^2\right)\cdot\left(y^2\cdot y^5\right)\cdot z^2\)
\(=-150x^7y^7z^2\)
a, P=-3(x^3.x)(y^2.y^3)
=-3x^4y^5
b, Thay x=-1 , y=2 vào đơn thức P . Ta có :
P=-3.(-1)^4.2^5
P=3.1.32
P=96
