Cố giúp mk nha mai mk đi học nhưng ko pik làm cố giupws nha cảm ơn các bn
tính giá trị của biểu thức sau: \(M=\frac{\left(\frac{2}{3}\right)^3\cdot\left(\frac{-3}{4}\right)^2\cdot\left(-1\right)^{2013}}{\left(\frac{2}{5}\right)^2\cdot\left(\frac{-5}{12}\right)^3}\)
ai trả lời đc thì nhanh giùm mk nha mai kiểm tra ùi
