Алгебра: Сократите дробь 1) m^2-3m/(m-3)^2 2) 4x-4y/ 8x 3) 8b-4/12b+16 4) p-pq/p+pq 5) a^2b-ab^2/ab^3 6) 5a+15b/3b+a 7) 2a-4b/16a-8b

jcyueurur · Answer

1)m^2-3m/(m-3)^2=m(m-3)/(m-3)^2=m/m-32)4x-4y/8x=4(x-y)/8y=x-y/2y3)8b-4/12b+16=4(2b-1)/4(3b+4)=2b-1/3b+44)p-pq/p+pq=p(1-q)/p(1+q)=1-q/1+q5)a^2b-ab^2/ab^3=ab(a-b)/ab^3=a-b/b^26)5a+15b/3b+a=5(a+3b)/3b+a=57)2a-4b/16a-8b=2(a-2b)/8(2a-b)=a-2b/4(2a-b)...
