Question

0,2xy²*5yx² x=0,125 y=0,8

Answer 1

Ответ:

$0.001$

Объяснение:

$0.2xy {}^{2} \times 5yx {}^{2} = \\ = 1 \times x {}^{3} y {}^{3} = \\ = x {}^{3} y {}^{3} = \\ = (0.125) {}^{3} \times (0.8) {}^{3} = \\ = 0.00195 \times 0.512 = \\ = 0.001$

Answer 2

To evaluate the expression 0.2xy² * 5yx² when x = 0.125 and y = 0.8, you can substitute these values into the expression and calculate the result step by step.

1. Substitute the values of x and y into the expression:

0.2 * (0.125) * (0.8)² * 5 * (0.8) * (0.125)²

2. Calculate each part of the expression separately:

0.2 * 0.125 = 0.025 (0.8)² = 0.64 (0.125)² = 0.015625

3. Now, multiply all the calculated parts together:

0.025 * 0.64 * 5 * 0.8 * 0.015625

4. Perform the multiplications:

0.025 * 0.64 * 5 * 0.8 * 0.015625 = 0.000512

So, when x = 0.125 and y = 0.8, the expression 0.2xy² * 5yx² evaluates to 0.000512.
