BAI1 :phuong trinh vo nghiem neu tham so m bang bao nhieu biet :
m^2x+m=3mx+3
BAI2 : ba so thuc x,y,z co x+y+z =114 va xyz=46656. neu y=xk ; z=xk^2 thi x+z bang bao nhieu ?
xyz=46656
\(\Leftrightarrow x.xk.xk^2=46656\Leftrightarrow x^3.k^3=46656\Leftrightarrow\left(xk\right)^3=46656\Rightarrow xk=36\)Ta có xk=36=> y=36
Vậy \(x+z=114-y=114-36=78\)
x - 5 / 12 = 2 / 3 - 1 / 4 bang bao nhieu vay cac ban
X - \(\frac{5}{12}\) = \(\frac{2}{3}\) - \(\frac{1}{4}\)
X - \(\frac{5}{12}\) = \(\frac{5}{12}\)
X = \(\frac{5}{12}\) + \(\frac{5}{12}\)
X = \(\frac{10}{12}\) = \(\frac{5}{6}\) TK MÌNH NHÉ BẠN
