Question

1,6²+0,8*1,6-2,4*2,6

Answer 1

=1,6*(1,6+0,8)-2,4*2,6=1,6*2,4-2,4*2,6=2,4*(1,6-2,6)=2,4*(-1)=-2,4

Answer 2

1. 1,6*1.6=2,56
2. 0,8*1,6=1,28
3. 2,4*2,6=6,24
4. 2,56 + 1,28 = 3,84
5. 3,84 - 6,24 = -2,4
Ответ: -2,4

Answer 3

To solve the given expression:

1. Calculate the square of 6: 6² = 6 * 6 = 36

2. Multiply 0.8 by 1.6: 0.8 * 1.6 = 1.28

3. Multiply 2.4 by 2.6: 2.4 * 2.6 = 6.24

Now, substitute the results back into the expression:

36 + 1.28 - 6.24

Next, perform the addition and subtraction:

36 + 1.28 = 37.28 37.28 - 6.24 = 31.04

Therefore, the value of the expression 1,6² + 0,8 * 1,6 - 2,4 * 2,6 is 31.04.
