Question

3m - 9m²-1\3m при m=1\9

Answer 1

(3m+6m)/9=9m/9=m

то есть ответ: -12 и -5,96

значит

(5,2a-5,2b)/5,2=5,2(a-b)/5,2=a-b=-27-(-3,64)=-23,36=26,4

Answer 2

To evaluate the expression 3m - 9m² - 1/3m when m = 1/9, you simply need to substitute the value of m into the expression and perform the calculations.

Step 1: Substitute m with 1/9 in the expression: 3(1/9) - 9(1/9)² - 1/(3 * 1/9)

Step 2: Simplify the terms: 1/3 - 9(1/81) - 1/(1/3)

Step 3: Continue simplification: 1/3 - 1/9 - 3

Step 4: Find a common denominator, which is 9: (3/9) - (1/9) - (27/9)

Step 5: Combine the terms: (3 - 1 - 27) / 9

Step 6: Perform the final calculation: -25 / 9

So, when m = 1/9, the value of the expression 3m - 9m² - 1/(3m) is -25/9.
