Question

4²+10²-2×4×10×(-1/2)​

Answer 1

Ответ:

-1/2 = -0,5

Будем делать по действиям.

1)4 * 4 = 16

2) 10 * 10= 100

3) 2 * 4 = 8

4) 8 * 10 = 80

5) 80 * -0,5 = -40

6) 16 + 100 = 116

7) 116 - (-40) = 156

Ответ: 156.

Объяснение:

Answer 2

To simplify the expression 4² + 10² - 2 × 4 × 10 × (-1/2), we can perform the calculations step by step:

4² = 4 × 4 = 16 10² = 10 × 10 = 100

Now, let's simplify the last term:

2 × 4 × 10 × (-1/2) = 2 × 4 × 10 × -1/2 = -40

Now we can substitute these values back into the original expression:

4² + 10² - 2 × 4 × 10 × (-1/2) = 16 + 100 - (-40)

Since we have a negative sign before -40, we can simplify the expression further:

16 + 100 + 40 = 156

Therefore, the simplified value of the expression 4² + 10² - 2 × 4 × 10 × (-1/2) is 156.
