Answer 1

1)10"2-7"2=100-49=5110"2 это 10x10 = 100 а 7х7+49
2)5"3-5"2=125-25=1005"3 это 5х5х5=125 тоесть 5х5=25 и 25х5=125
а 5"2 это 5х5=25 

Answer 2

Calculation 1: 10^2 - 7^2

To calculate 10^2 - 7^2, we need to first calculate the squares of 10 and 7, and then subtract the result.

- The square of 10 is 100. - The square of 7 is 49.

Now, subtracting 49 from 100 gives us the result:

10^2 - 7^2 = 100 - 49 = 51.

Calculation 2: 5^3 - 5^2

To calculate 5^3 - 5^2, we need to first calculate the cubes of 5 and the square of 5, and then subtract the result.

- The cube of 5 is 125. - The square of 5 is 25.

Now, subtracting 25 from 125 gives us the result:

5^3 - 5^2 = 125 - 25 = 100.

Therefore, the answers to the calculations are: 1) 10^2 - 7^2 = 51. 2) 5^3 - 5^2 = 100.
