Answer:

Step-by-step explanation:

Okay! This question is a very simple one, but without a calculator, your answer could easily vary from others! So, let´s do this one together!

The equation:

0.810x0.00048/0.000400x0.027

Let´s do the top :

0.810 x 0.00048 = 0.0003888

I will leave these numbers the same until the last part, lets not round them.

Bottom:

0.0004 x 0.027 = 0.0000108

And again I am not going to round this number.

Now we can divide!

0.0003888/0.0000108 = 36

I hope this helped!

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

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

Start by decomposing the number inside the root into primes

Then group the terms into cubes if possible

$\begin{gathered} 80=2\cdot2\cdot2\cdot2\cdot5 \\ 80=2^3\cdot2\cdot5 \\ 80=10\cdot2^3 \end{gathered}$

rewrite the root

$\sqrt[3]{80}=\sqrt[3]{10\cdot2^3}$

then cancel the terms that are cubes and bring them out of the root

$\sqrt[3]{80}=2\sqrt[3]{10}$
