Answer 2

To simplify the given expression, we'll use the formula for the product of two binomials, which is:

(a + b) * (a - b) = a^2 - b^2

In this case, the expression is in the same format as the formula, with a = 10x³y and b = 1/(9xy²). So, we can apply the formula to simplify it:

(10x³y - 1/(9xy²)) * (10x³y + 1/(9xy²)) = (10x³y)² - (1/(9xy²))²

Now, let's simplify the squared terms:

(10x³y)² = (10x³y) * (10x³y) = 100x^6y²

(1/(9xy²))² = (1/(9xy²)) * (1/(9xy²)) = 1/(81x²y⁴)

Now, the simplified expression is:

100x^6y² - 1/(81x²y⁴)
