(2y³-0,5y²)²

Ответ: (2у³-0,5у²)²

To solve this expression, we need to apply the exponent to each term inside the parentheses separately.

First, let's square the first term: (2у³)² = 4у⁶

Next, let's square the second term: (-0,5у²)² = 0,25у⁴

Now, we can combine the squared terms together: (4у⁶ + 0,25у⁴)

So, the simplified expression is 4у⁶ + 0,25у⁴.
