Answer 1

Ответ:

-10√7, т.к. 4*(-2,5)=-10

Answer 2

To simplify the expression, let's perform the calculations step by step:

Step 1: Simplify the expression inside the parentheses: -2.5 * √7

Step 2: Multiply the result from Step 1 by √7: -2.5 * √7 * √7 = -2.5 * 7 = -17.5

Step 3: Take the 4th root of -17.5: 4√(-17.5) ≈ -2.6263 (rounded to four decimal places)

So, 4th root of 7 * (-2.5 * √7) ≈ -2.6263.
