nella27o A)=15xyxy=15x²yy=15x²y²
d)= -(4x/2)*(-2x/4)= -(-2x)(-0,5x)= -(-2x(-0,5x))= -(-(-2x*0,5x))= -(-(-xx))= -(-(-x²)= -x²
e)=x/2+1/2+2x-1/4=x/2+0,5+2x/4-1/4=x/2+0,5+0,5x-1/4=x+0,5-0,25=x+0,25
g)=3a²-12+a²-2=4a²-12-2=4a²-14

arkadycyb a)=15xyxy=15x²yy=15x²y² d)= -(4x/2)*(-2x/4)= -(-2x)(-0,5x)= -(-2x(-0,5x))= -(-(-2x*0,5x))= -(-(-xx))= -(-(-x²)= -x² e)=x/2+1/2+2x-1/4=x/2+0,5+2x/4-1/4=x/2+0,5+0,5x-1/4=x+0,5-0,25=x+0,25 g)=3a²-12+a²-2=4a²-12-2=4a²-14

animaldk $a)\ 5xy\cdot3xy=15x^2y^2\\\\d)\ -4\cdot(-\frac{x}{2})\cdot(-\frac{2x}{4})=2x\cdot(-\frac{x}{2})=-x^2\\\\e)\ \frac{x+1}{2}+\frac{2x-1}{4}=\frac{2(x+1)}{4}+\frac{2x-1}{4}=\frac{2x+2+2x-1}{4}=\frac{4x+1}{4}=x+\frac{1}{4}\\\\g)\ 3(a^2-4)-(-a^2+2)=3a^2-12+a^2-2=4a^2-14$
