Question

4) -5 √0,36x², x < 0.​

Answer 1

Объяснение:

-5√0,36х²=-5×0,6√х²= 30х²

Answer 2

If $x < 0$, we can simplify the expression $-5 \sqrt{0.36x^2}$ as follows:

First, let's simplify the expression inside the square root:

$\sqrt{0.36x^2} = \sqrt{0.36} \cdot \sqrt{x^2} = 0.6 \cdot \left| x \right|$

Since $x < 0$, we take the absolute value of $x$ to ensure a positive result.

Now we can substitute this simplified expression back into the original equation:

$-5 \sqrt{0.36x^2} = -5 \cdot 0.6 \cdot \left| x \right| = -3 \left| x \right|$

Therefore, if $x < 0$, the expression $-5 \sqrt{0.36x^2}$ simplifies to $-3 \left| x \right|$.
