Answer 3

To evaluate the expression "0,12A - B3" when A = 0,4 and B = 0,3, you simply substitute the values of A and B into the expression and perform the calculations.

Given: A = 0.4 B = 0.3

Now, let's calculate:

0.12A - B3

Substitute the values of A and B:

0.12 * 0.4 - 0.3^3

Now perform the calculations step by step:

0.12 * 0.4 = 0.048

0.3^3 = 0.3 * 0.3 * 0.3 = 0.027

Finally, subtract:

0.048 - 0.027 = 0.021

So, the result of "0.12A - B3" when A = 0.4 and B = 0.3 is 0.021.
