Ответ:

В решении.

Объяснение:

1) Определить степень многочлена:

Степенью многочлена называется наибольшая из степеней его слагаемых.

1) 2ху + 4х²у + 1,3х³у²;

Наибольшая: (х³у²); 3 + 2 = 5 степень многочлена;

2) 4х⁵у + 3х²у + 1,3х³у²;

Наибольшая: (х⁵у); 5 + 1 = 6 степень многочлена;

3) 2х²у³ + 4х²у + 1,3х⁶у²;

Наибольшая: (х⁶у²); 6 + 2 = 8 степень многочлена.

2) Привести многочлен к стандартному виду:

Записать многочлен в стандартном виде, т.е., в порядке убывания степеней и в алфавитном порядке.

1) 4х⁵у + 3х²у + 1,3х³у² = 4х⁵у + 1,3х³у² + 3х²у;

2) 2х²у³ + 4х²у + 1,3х⁶у² = 1,3х⁶у² + 2х²у³ + 4х²у;

3) 2х⁴у² + 4х²у + 1,3х³у² = 2х⁴у² + 1,3х³у² + 4х²у.
