Question

A(b-3a)^2/3a^2-ab  при a=1 b=2

Answer 1

Ответ:

1

Объяснение:

1) B - 3a = 2 - 3*1 = -1

2) (-1)^2 = 1

3) 1*1 = 1

4) 3a^2 = 3*1^2 = 3

5) 3 - 2 = 1

6) 1/1 = 1

Answer 2

To evaluate the expression A(b-3a)^2/3a^2-ab with a=1 and b=2, simply substitute the values of a and b into the expression and perform the calculations.

Let's plug in the values:

A(b-3a)^2/3a^2 - ab

With a = 1 and b = 2:

A(2 - 3 * 1)^2 / 3 * 1^2 - 1 * 2

Now, perform the calculations:

A(2 - 3)^2 / 3 - 2

A(-1)^2 / 3 - 2

A(1) / 3 - 2

A/3 - 2

Since we don't have the value of A, we cannot provide the exact numerical result. The answer would depend on the value of A, which is not given in the question. However, the expression's simplified form with the given values of a and b is A/3 - 2.
