Answer 2

1. To solve the first expression, let's break it down step by step:

1/225 * 64 - 8400

First, let's simplify the division:

0.004444444 * 64 - 8400

Next, let's perform the multiplication:

0.284444444 - 8400

Finally, let's subtract:

-8399.715555556

Therefore, the result of the expression 1/225 * 64 - 8400 is approximately -8399.715555556.

2. To solve the second expression, let's break it down step by step:

1405 + 75 in square + 9

First, let's calculate the square:

75^2 = 5625

Next, let's perform the addition:

1405 + 5625 + 9

Finally, let's add the numbers:

7039

Therefore, the result of the expression 1405 + 75 in square + 9 is 7039.

3. To solve the third expression, let's break it down step by step:

3/18 in square - 11 in square + 13 in square

First, let's simplify the division:

0.166666667 in square - 11 in square + 13 in square

Next, let's calculate the squares:

0.027777778 - 121 + 169

Finally, let's perform the addition and subtraction:

48.027777778

Therefore, the result of the expression 3/18 in square - 11 in square + 13 in square is approximately 48.027777778.

4. To solve the fourth expression, let's break it down step by step:

203 in square - 19 * 794

First, let's calculate the square:

203^2 = 41209

Next, let's perform the multiplication:

19 * 794 = 15086

Finally, let's subtract:

41209 - 15086

Therefore, the result of the expression 203 in square - 19 * 794 is 26123.
