Question

-2x*(-4,7y)9m*2 2/3n*(-1 11/12m)​

Answer 1

Ответ:

Пошаговое объяснение:

-2х * (-4,7у) = (-2 * (-4,7) ) * х * у = 9,4ху

9m * 2 2/3n * (-1 11/12m) =

9m * 8/3n * (-23/12m) =

(9m * 8/3n) * (-23/12m) =

72/3mn * (-23/12m) =

24mn * (-23/12m) =

2mn * (-23/1m) = -46/1 m²n = -46m²n

Answer 2

It seems like you've provided a mathematical expression with variables and operations. Let's break it down step by step:

-2x*(-4.7y)9m2 2/3n(-1 11/12m)

First, let's rewrite the expression with proper multiplication signs:

-2x * (-4.7y) * 9m * 2 2/3n * (-1 11/12m)

Next, we can simplify it further by performing the operations:

-2x * (-4.7y) = 9.4xy 9m * 2 = 18m 2 2/3n = 8/3n

Now the expression becomes:

9.4xy * 18m * (8/3)n * (-1 11/12m)

Next, we can combine like terms:

(9.4 * 18 * -1)xy * (8/3)n * (11/12)m

-169.2xy * (8/3)n * (11/12)m

Finally, we can express the result in standard form:

-169.2 * (8/3) * 11/12 * x * y * n * m

This simplifies to:

-397.6xy * n * m
