Question

-0.1 √400а⁶ если а<0

Answer 1

Ответ:

$\sqrt{400 {a}^{6} } = 200 \times {a}^{3} \\ - 0.1 \times 200 \times {a}^{3} = - 20 \times {a}^{3} \\ a < 0 < = > - 20 \times {a}^{3} > 0$

Объяснение:

Минус при умножении на минус дает плюс

Answer 2

If $a < 0$, the expression $-0.1 \sqrt{400a^6}$ can be simplified as follows:

First, let's simplify the inside of the square root: $\sqrt{400a^6} = \sqrt{(20a^3)^2} = 20a^3$

Next, multiply by -0.1: $-0.1 \times 20a^3 = -2a^3$

Therefore, the simplified expression is $-2a^3$.
