Explanation

$Force = Mass\ \times acceleration$ $= \lbrack M\rbrack\left\lbrack LT^{- 2} \right\rbrack = \lbrack MLT^{- 2}\rbrack$ $Torque = Force\ \times distance = \left\lbrack MLT^{- 2} \right\rbrack\lbrack L\rbrack = \lbrack ML^{2}T^{- 2}\rbrack$ $Work = Force\ \times distance = \left\lbrack MLT^{- 2} \right\rbrack\lbrack L\rbrack = \lbrack ML^{2}T^{- 2}\rbrack$ $Energy = \lbrack ML^{2}T^{- 2}\rbrack$ $Power = \frac{Work}{Time} = \frac{\lbrack ML^{2}T^{- 2}\rbrack}{\lbrack T\rbrack} = \lbrack ML^{2}T^{- 3}\rbrack$
