Question

6a(2b-3a)+2(3a-b)^2 Если a=10,15 b=2

Answer 1

Ответ:

8

Объяснение:

6a(2b - 3a) + 2(3a - b)^2 = 6*10,15*(2*2 - 3*10,15) + 2(3*10,15 - 2)^2 =

= 60,9(4 - 30,45) + 2(30,45 - 2)^2 = -60,9*26,45 + 2*28,45^2 =

= -1610,805 + 1618,805 = 8

Answer 2

To evaluate the expression 6a(2b-3a)+2(3a-b)^2 when a=10 and b=2, we simply substitute the values of a and b into the expression and perform the calculations:

Given: a = 10, b = 2

Expression: 6a(2b-3a) + 2(3a-b)^2

Step 1: Substitute the values of a and b into the expression.

6 * 10(2 * 2 - 3 * 10) + 2(3 * 10 - 2)^2

Step 2: Perform the calculations inside the parentheses first.

6 * 10(4 - 30) + 2(30 - 2)^2

Step 3: Perform the multiplications inside the parentheses.

6 * 10(-26) + 2(28)^2

Step 4: Perform the remaining operations.

60 * (-26) + 2 * 784

Step 5: Continue with the calculations.

-1560 + 1568

Step 6: Finally, sum up the result.

-1560 + 1568 = 8

Therefore, when a=10 and b=2, the value of the expression 6a(2b-3a)+2(3a-b)^2 is 8.
