Question

1,3m-3,4*(2m-0,6*(3m+4)) m-???

Answer 1

1,3m-3,4(2m-1,8m-2,4)=1,3m-3,4(0,2m-2,4)=0,62m+8,16

Answer 2

Let's solve the expression step by step:

1. Distribute the multiplication inside the innermost parentheses: 3m + 4

2. Multiply 0.6 by the result of the previous step: 0.6 * (3m + 4) = 1.8m + 2.4

3. Now, substitute the result of step 2 into the expression: 2m - 0.6 * (3m + 4) = 2m - (1.8m + 2.4)

4. Distribute the subtraction inside the parentheses: 2m - (1.8m + 2.4) = 2m - 1.8m - 2.4

5. Combine like terms: 2m - 1.8m = 0.2m

6. Finally, subtract 2.4 from the result of step 5: m - 0.2m - 2.4 = 0.8m - 2.4

So, the simplified expression is: m - 0.8m - 2.4
