Вот решение, поставь спасибо)

Answer 2

Let's calculate each expression step by step:

1. -4/5 * (-5/16):

To multiply fractions, you simply multiply the numerators (the top numbers) together and the denominators (the bottom numbers) together.

(-4/5) * (-5/16) = (4 * 5) / (5 * 16)

Now, simplify the fractions:

(20) / (80)

You can simplify this fraction further by dividing both the numerator and denominator by their greatest common divisor, which is 20:

(20/20) / (80/20) = 1/4

So, -4/5 * (-5/16) = 1/4.

2. (-1/3)²:

To square a fraction, you simply square the numerator and square the denominator:

(-1/3)² = (-1)² / (3)²

Now, calculate the squares:

(1) / (9)

So, (-1/3)² = 1/9.

To summarize: -4/5 * (-5/16) = 1/4 (-1/3)² = 1/9
