Объяснение:(-2:3)^4-(2:9)^9=-18,6-0,4=-19

Answer 2

1. (-2/3)^4=4/9
2. (2/9)^2=4/81
3. 4/9 делить на 4/81 = 4/9 * 81/4
Четыре сокращаем, 81 сокращаем 9 = 9
Ответ: 9

Answer 3

Let's calculate the expression step by step:

1. First, calculate (-2/3)^4: (-2/3)^4 = (-2/3) * (-2/3) * (-2/3) * (-2/3) = 16/81

2. Next, calculate (2/9)^2: (2/9)^2 = (2/9) * (2/9) = 4/81

3. Now, subtract the result of (2/9)^2 from (-2/3)^4: (16/81) - (4/81) = (16 - 4) / 81 = 12/81

4. Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (which is 3 in this case): (12/3) / (81/3) = 4/27

So, (-2/3)^4 - (2/9)^2 = 4/27.
