Answer 1

Вот, надеюсь что все понятно)))

Answer 2

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

1. 5 * 29 - 27 * 5 / 37 * 12 - 35 * 12

Using the order of operations (parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right), we perform the multiplication and division first:

= 145 - 135 / 37 * 12 - 420

Next, we calculate the division:

= 145 - (135 / 37) * 12 - 420

Then, we calculate the multiplication:

= 145 - (3.6486486486486487) * 12 - 420

= 145 - 43.78378378378379 - 420

Finally, we perform the subtraction:

= -318.7837837837838 - 420

= -738.7837837837838

Therefore, the value of the expression 5 * 29 - 27 * 5 / 37 * 12 - 35 * 12 is approximately -738.78.

2. 36 * 99 - 98 * 36 / 20 * 16 - 20 * 14

Using the order of operations, we perform the multiplication and division first:

= 3,564 - 3,528 / 320 - 280

Next, we calculate the division:

= 3,564 - (3,528 / 320) - 280

Then, we calculate the multiplication:

= 3,564 - (11.025) - 280

= 3,564 - 11.025 - 280

Finally, we perform the subtraction:

= 3,273.975 - 280

= 2,993.975

Therefore, the value of the expression 36 * 99 - 98 * 36 / 20 * 16 - 20 * 14 is approximately 2,993.975.
