2) 289 - 209 = 80
3) 36 : 3 = 12

Answer 3

Calculation of Expressions

To calculate the given expressions, let's break them down step by step:

1. 9 raised to the power of 2 minus 19:

To calculate this expression, we first need to raise 9 to the power of 2 and then subtract 19 from the result.

The calculation would be as follows:

9^2 - 19 = 81 - 19 = 62

Therefore, the value of 9 raised to the power of 2 minus 19 is 62.

2. 17 raised to the power of 2 minus 209:

Similar to the previous expression, we need to raise 17 to the power of 2 and then subtract 209 from the result.

The calculation would be as follows:

17^2 - 209 = 289 - 209 = 80

Therefore, the value of 17 raised to the power of 2 minus 209 is 80.

3. 6 raised to the power of 2 divided by 3:

To calculate this expression, we need to raise 6 to the power of 2 and then divide the result by 3.

The calculation would be as follows:

(6^2) / 3 = 36 / 3 = 12

Therefore, the value of 6 raised to the power of 2 divided by 3 is 12.
