Алгебра: Cos(п/3)*cos(2п/3)*cos(4п/3)*cos(8п/3)*cos(16п/3)=

Aieks01 · Accepted Answer

1) 15x+y-3x-7y-3 =12x-6y-3
2)3y-6+2y+5 =5y-1
3)2x-5xy-3y+2xy+5y-3x=-x+2y-3xy
4)3x-2+3-7x=-4x+1
5)5-3a+2a-4+3-8a =4-9a

1)5(x-5) =5x-25
2)-2(y+2) =-2y-4
3)8(2-3x) =16-24x
4)-4(x-6) =-4x+24
5)3(5-2a)=15-6a

Cos(п/3)cos(2п/3)cos(4п/3)cos(8п/3)cos(16п/3)=
