Question

((−51)^0)^5 − 9^2 ⋅ 1/9 − 5^2 ⋅ 0,2

Answer 1

Ответ:

-13

Пошаговое объяснение:

Answer 2

Let's break down the expression step by step:

1. ((-51)^0)^5: Any number raised to the power of 0 is equal to 1. Therefore, (-51)^0 equals 1. Then, raising 1 to the power of 5 still gives us 1. So, ((-51)^0)^5 simplifies to 1^5, which is 1.

2. 9^2: The exponent 2 means we multiply 9 by itself, so 9^2 equals 9 * 9, which is 81.

3. 1/9: This fraction means we take the reciprocal of 9. So, 1/9 equals 1 divided by 9, which is approximately 0.1111.

4. 5^2: The exponent 2 means we multiply 5 by itself, so 5^2 equals 5 * 5, which is 25.

5. 0.2: This is a decimal number, 0.2.

Now, let's substitute these values back into the original expression:

1 - 81 * 0.1111 - 25 * 0.2

Calculating each part separately:

1 - 9.0009 - 5

Finally, adding and subtracting:

-13.0009

Therefore, the value of the expression ((-51)^0)^5 - 9^2 * 1/9 - 5^2 * 0.2 is approximately -13.0009.
