Question

3m³n - 2 - 3mn² + 4m³n - 7​

Answer 1

Ответ:

3m³n - 2 - 3mn² + 4m³n - 7=7m³n-9-3mn²

Answer 2

It seems like you want to simplify the expression: 3m³n - 2 - 3mn² + 4m³n - 7.

To simplify this expression, you can combine like terms, which means adding or subtracting terms with the same variables and exponents:

3m³n + 4m³n - 2 - 3mn² - 7

Now, combine the like terms:

(3m³n + 4m³n) - (3mn² + 2 + 7)

Combine the terms with 'm³n':

(3m³n + 4m³n) = 7m³n

Combine the constants (2 and 7):

• (3mn² + 2 + 7) = - (3mn² + 9)

Now, put it all together:

7m³n - (3mn² + 9)

So, the simplified expression is:

7m³n - 3mn² - 9
