Answer 2

To calculate the expression (а+1)(а-1)(а²+1)-(9-а²)² when а=3, we simply substitute the value of а into the expression and perform the arithmetic operations.

Let's do the calculations step by step:

Step 1: Substitute the value of а=3 into the expression (а+1)(а-1)(а²+1)-(9-а²)²

(3+1)(3-1)(3²+1)-(9-3²)²

Step 2: Perform the operations inside the parentheses.

(4)(2)(10)-(9-9)²

Step 3: Continue with the arithmetic.

(4)(2)(10)-0²

Step 4: Simplify further.

(8)(10)

Step 5: Final calculation.

80

So, when а=3, the value of the expression (а+1)(а-1)(а²+1)-(9-а²)² is 80.
