Question

3)-3√(-12)⁴4)-√5²•14⁴вычислите ​

Answer 1

Ответ:

3) $-3\sqrt{(-12)^{4}}=-432$

4) $-\sqrt{5^{2}*14^{4}} =-980$

Объяснение:

3) $-3\sqrt{(-12)^{4}}=-3 \sqrt{12^{4}}=-3*12^{2}=-3*144=-432$

4) $-\sqrt{5^{2}*14^{4}} =-5*14^{2}=-5*196=-980$

Answer 2

Let's break down the expression step by step:

1. First, let's simplify the expression -3√(-12)^4:

The negative sign outside the cube root can be written as a negative inside the cube root with an even exponent.

-3√(-12)^4 = -3√((-12)^2) = -3√(144) = -3 * 2 = -6

2. Now, let's simplify the expression -√(5^2 * 14^4):

-√(5^2 * 14^4) = -√(25 * 14^4) = -√(25 * (14^2)^2) = -√(25 * 196^2) = -√(25 * 38416) = -√960400 = -980

So, the final result is:

-6 - 980 = -986
