Question

(1-√441)(1+√441)с решением

Answer 1

По формуле (a-b)(a+b)= $a^{2} - b^{2}$

Тогда,

(1-√441)(1+√441)=1-441=-440

Answer 2

To solve the expression (1 - √441)(1 + √441), we first need to simplify it.

Step 1: Find the value of √441 √441 = √(21^2) = 21

Step 2: Substitute the value of √441 into the expression: (1 - 21)(1 + 21)

Step 3: Perform the operations inside the parentheses: (-20)(22)

Step 4: Multiply the numbers: -20 * 22 = -440

So, (1 - √441)(1 + √441) = -440.
