Question

8а²b²(3аb-7а)-4аb(2а²b²+4а²b)

Answer 1

24a³b³-56a³b²-8a³b³-16a³b²=-72a³b²+16a³b³

Answer 2

8а²б²(3аб-7а)-4аб(2а²б²+4а²б)=24а³б³-56а³б²-8а³б³-16а³б²=16а³б³-72а³б²

Answer 3

To simplify the given expression, let's follow the order of operations (PEMDAS) and perform the required calculations step by step:

1. Distribute the terms inside the parentheses: 8a²b²(3ab - 7a) - 4ab(2a²b² + 4a²b)

   = (8a²b² * 3ab) - (8a²b² * 7a) - (4ab * 2a²b²) - (4ab * 4a²b)

2. Multiply the terms: = 24a³b³ - 56a³b² - 8a³b³ - 16a³b²

3. Combine like terms: = (24a³b³ - 8a³b³) + (-56a³b² - 16a³b²)

4. Simplify further: = 16a³b³ - 72a³b²

So, the simplified expression is 16a³b³ - 72a³b².
