1 + {[(1 * 0.5) x 12] x 3}

1 + {[0.5 x 12] x 3}

1 + {6 x 3}

1 + 18

I'm not sure if that's a 1.000 or 1,000 so:

1,000 + {[(1,000 * .5) x 12] x 3}

1,000 + {[500 x 12] x 3}

1,000 + {6,000 x 3}

1,000 + 18,000

Tính đạo hàm của y=2x-1-căn3x-0
adoni [48]

Answer:

The derivative is

\frac{dy}{dx} = 2 -  \frac{2\sqrt3}{\sqrt x}\\

Step-by-step explanation:

The function is given by

y = 2x - 1 - \sqrt {3x}

Differentiate with respect to x, we get

\frac{dy}{dx} = 2 - 0 - \frac{2\sqrt3}{\sqrt x}\\\\\frac{dy}{dx} = 2 -  \frac{2\sqrt3}{\sqrt x}\\
