Answer 2

To simplify the expressions, let's perform the calculations step by step:

1. -6х^3у(-5)

Since there's no variable for 'х', we can rewrite the expression as follows: -6 * (-5) = 30

Result: 30

2. 1 7/9а(-3/4б) * 2 1/3

Let's convert mixed fractions to improper fractions: 1 7/9 = (9 + 7) / 9 = 16/9 2 1/3 = (3 + 2) / 3 = 5/3

Now, multiply the fractions: (16/9) * (-3/4б) * (5/3) = - (16/9) * (3/4б) * (5/3) (since 'а' and 'б' are separate variables)

The '3's in the denominators cancel out, and the result is: = - (16/9) * (1/4б) * (5) = - (4/9б) * (5)

Result: - (20/9б) or -20/9б

3. 4,2m(-1,8) * (-2,5п)

When multiplying, you can ignore the commas: 4.2m * (-1.8) * (-2.5п) = -7.56m * (-2.5п)

Result: -7.56m * (-2.5п) or 7.56m * 2.5п (since negative * negative = positive)

4. -16,2р(-2/9) * (-5/18)

Again, ignore the commas when performing the calculations: -16.2р * (-2/9) * (-5/18) = -16.2р * (10/162) = -16.2р * (5/81)

Result: -16.2р * (5/81) or -0.2р * р

Please note that the letter "р" in Russian Cyrillic looks like "p" in Latin script. So, the final result is -0.2p^2.
