Answer 1

Ответ:

0

Объяснение:

=(15-0)*(15-0)-225=15*15-225=225-225=0

Answer 2

Let's solve the expression step by step:

(5 * 3 - 10 * 0.01) * (5 * 3 + 10 * 0.01) - 25 * 9

First, perform the calculations within the parentheses:

(15 - 0.1) * (15 + 0.1) - 225

Now multiply the terms within the first set of parentheses:

14.9 * 15.1 - 225

Now multiply the two values:

224.99 - 225

Finally, subtract 225 from 224.99:

-0.01

So, the result of the expression is -0.01.
