A)24x-18=24x-18 imeet mnojestvo kornei
b)15x-21=15x+20
-21 ne ravno 20
ne imeet kornei
v)12x+1=12x+1 mnojestvo kornei
g)18x+6=4+24x
24x-18x=6-4
6x=2
x=1/3
1) y * y^6 * y^3 = y^1+6+3 = y^10
2) y^24 / y^6 = y^24-6 = y^18
3) (y^5)^4 = y^5*4 = y^20
1) у=(-2-2х)/6 у(8)=(-2-2*8)/6= -3
2)у=(5-3х)/ (-4) у(3)=(5-3*3)/(-4)= 1
-90+0,7*(-10)³=-90+0,7*(-1000)=-90-700=-790
