Question

Вычисли: 1)[-12,8]= 2) {328,07} С объяснением.

Answer 1

Ответ:

Целой частью [x] числа "х" называется наибольшее целое, не превосходящее "х".

$[-12,8]=-13\; \; \; (-13$

Дробной частью  $\{x\}$   числа "х" называется число  $\{x\}=x-[x]$  .

$\{328,07\}=328,07-[328,07]=328,07-328=0,7$

Answer 2

Ответ:

Объяснение:

[x]-целая часть числа х, {x}- дробная часть числа х

x=[x]+{x}

1)-12,8=-13+0,2;  

-13- целая часть равна -13

[-12,8]= -13

2) 328,07=328+0,7

0,7- дробная часть числа 328,07

{328,07}= 0,7

Answer 3

1. [-12, 8]:

The expression [-12, 8] represents an interval. An interval is a set of real numbers that includes all the numbers between two specified values, including the endpoints. In this case, the interval [-12, 8] includes all real numbers x that satisfy -12 ≤ x ≤ 8.

So, the interval [-12, 8] consists of all the real numbers starting from -12 and going up to 8, including both -12 and 8.

2. {328, 07}:

It seems there might be a typo in the expression. The correct representation for a set of numbers would not have a comma between the elements. It should be written as {328, 07} or {328, 7}. Assuming you meant {328, 7}, this represents a set with two elements: 328 and 7.

A set is an unordered collection of distinct elements. Therefore, the set {328, 7} contains only two specific values, 328 and 7, without any particular order.

If there was a comma between the elements like {328, 07}, it would be interpreted as two separate elements: 328 and 7, because leading zeros are not significant in the representation of integers. So, {328, 07} would be the same as {328, 7}.
