Answer 2

1)1,6•8= 12,8
2) как мы знаем, минус на минус дает плюс, поэтому при умножении мы получим положительное число: 1,6•8=12,8

Answer 3

To solve this expression, you can use the distributive property of multiplication over addition/subtraction:

a × (b - c) = a × b - a × c

So, for the given expression:

1. 1.6 × 8 = 12.8
2. 1.6 × (-8) = -12.8 (when you multiply a positive number by a negative number, the result is negative)

Now, substitute these values back into the expression:

1.6 × 8 - 1.6 × (-8) = 12.8 - (-12.8)

When you subtract a negative number, it is the same as adding its positive counterpart, so:

12.8 - (-12.8) = 12.8 + 12.8

Now, perform the addition:

12.8 + 12.8 = 25.6

So, the result of the expression is 25.6.
