2. разложить на множители: а) a(2n – 1) + 3(2n – 1); б) 2c – 2d + bc – bd.

1. y=(4x+1)/(3-2x)

y'=[4(3-)*(4x+1)]/(3-2x)²=24/(3-2x)²

2. y=(3-4x²)³

y'=3(3-4x²)²*(3-4x²)'=-24x*(3-4x²)²

3. y=3sin(3x-π/3)

y'=3cos(3x-π/3)*(3x-π/3)'=9cos(3x-π/3)

4,6*10^4*2,5*10^-6=4,6*2,5*10^(4-6)=11,5*10^-2=11,5/100=0,115
