Question

A) 1,5•(-6) ²2²-5•(- 6)=

Answer 1

Ответ:         246.

Объяснение:

1,5•(-6) ²2²-5•(- 6)=1.5*36-4+5*6=54*4+30=216+30=246.

Answer 2

To evaluate the expression, let's break it down step by step:

1. Start by calculating the square of -6: (-6)² = 36.

2. Next, evaluate 2², which is equal to 4.

3. Now, multiply 1.5 by 36 and 4: 1.5 * 36 * 4 = 216.

4. Finally, subtract 5 multiplied by -6: 216 - (5 * -6).

To simplify the final part, multiply 5 by -6, which gives -30.

Thus, the final expression becomes: 216 - (-30).

When subtracting a negative number, it is equivalent to adding its positive counterpart. So, -(-30) becomes +30.

Therefore, the final result is: 216 + 30 = 246.
