Answer 1

(4a-b)(b+4a)=4ab+16a^2-b^2-4ab=16a^2-b^2. ^ -это степень. при решении используем формулу разности квадратов.

Answer 2

^2-это степень
(4a-b)(b+4a)
4аб + 16а^2-б^2-4аб
16а^2-б^2
Ответ : 16а^2-б^2

Answer 3

Multiplying (4a-b)(b+4a)

To multiply the expression (4a-b)(b+4a), we can use the distributive property, which states that for any real numbers a, b, and c, a(b + c) = ab + ac.

So, applying the distributive property to the given expression: ``` (4a - b)(b + 4a) = 4a * b + 4a * 4a - b * b - b * 4a ```

Simplifying further: ``` 4ab + 16a^2 - b^2 - 4ab ```

Finally, simplifying the expression: 16a^2 - b^2

Therefore, the result of multiplying (4a-b)(b+4a) is 16a^2 - b^2.
