Question

Не выполняя вычислений сравните значение выражений: -2,4•(-3,6)•7,8 и 9,6•(-4,1)•1,8​

Answer 1

Ответ:

Правая сторона больше

Пошаговое объяснение:

Т.к в ней два минуса, а минус на минус дает плюс. Справа только один минус. Положительное число больше отрицательного

Answer 2

Ответ:

первое больше и.к. оно положительное

Answer 3

To compare the values of the expressions without performing the actual calculations, we can use some estimation and basic arithmetic rules:

1. Signs: When multiplying two negative numbers, the result is positive. When multiplying a positive and a negative number, the result is negative.

2. Magnitudes: The magnitude of a number is its absolute value, ignoring the sign.

Now, let's compare the two expressions:

Expression 1: -2.4 * (-3.6) * 7.8 Expression 2: 9.6 * (-4.1) * 1.8

Estimations:

• The first expression involves three negative numbers being multiplied together. Since odd numbers of negative factors will produce a negative result, the result of the first expression is likely negative.

• The second expression involves two negative numbers being multiplied together and a positive number. Since even numbers of negative factors will produce a positive result, the result of the second expression is likely positive.

• We can ignore the decimals for now to simplify the comparison.

Comparison: The first expression is likely negative and the second expression is likely positive.

Therefore, without performing the actual calculations, we can conclude that the second expression (9.6 * (-4.1) * 1.8) will have a greater absolute value than the first expression (-2.4 * (-3.6) * 7.8).
