A. x - \(\dfrac{1}{15}\) = \(\dfrac{1}{10}\)

B. \(\dfrac{1}{3}\) + \(\dfrac{1}{2}\) : x = -4

C. ( x - 0,2 ) == 1,6

so sánh 

( -2 )\(^{300}\) và ( -3 )\(^{200}\)

A. x - \(\dfrac{1}{15}\) = \(\dfrac{1}{10}\)    B. \(\dfrac{1}{3}\) + \(\dfrac{1}{2}\) : x = -4    C. ( x - 0,2 ) = 1,6

A. \(\dfrac{3}{5}\) + \(\dfrac{-1}{3}\)    B. \(\dfrac{1}{12}\) - \((\dfrac{-1}{6}\) - \(\dfrac{1}{4})\)    C. \(\dfrac{1}{2}\) - \(\dfrac{-1}{3}\) + \(\dfrac{1}{23}\) + \(\dfrac{1}{6}\)
