3 ≥ 2

Істина.

Answer 2

To evaluate the expression -1^(2) + 1 * 1 + 1^(2), let's break it down step by step:

Step 1: Calculate the exponentiation (-1)^(2): (-1)^(2) means raising -1 to the power of 2. In this case, (-1)^(2) equals 1 because any number raised to an even power is always positive.

Step 2: Evaluate the multiplication 1 * 1: 1 * 1 equals 1 because the product of any number and 1 is the number itself.

Step 3: Add the results from Step 1 and Step 2: We have 1 (from Step 1) + 1 (from Step 2), which equals 2.

Now, let's compare the result (2) with the inequality statement:

2 ≥ 2

The inequality states that 2 is greater than or equal to 2. This statement is true because both sides are equal.

Therefore, the expression -1^(2) + 1 * 1 + 1^(2) ≥ 2 is true.
