If a = 7 and b = 3, what is the value of the expression 12a (2b)?

To solve the expression 12a(2b) when a = 7 and b = 3, we substitute the values:

12(7)(2)(3)

First, simplify within the brackets:

12 * 7 * 2 * 3 = 504

Therefore, the value of the expression is 504.

To find the value of the expression 12a (2b) when a = 7 and b = 3, follow these steps:

Step 1: Substitute the values of a and b into the expression.
12(7) (2(3))

Step 2: Simplify the multiplication within parentheses.
12 * 7 (2 * 3)

Step 3: Perform the multiplications.
84 (6)

Step 4: Simplify the expression.
84 * 6

Step 5: Perform the final multiplication.
504

Therefore, the value of the expression 12a (2b) when a = 7 and b = 3 is 504.

To find the value of the expression 12a (2b), we need to substitute the given values of a and b into the expression and perform the necessary calculations.

Given a = 7 and b = 3, we can plug these values into the expression:

12a (2b) = 12 * 7 (2 * 3)

First, we multiply 12 by 7:

12 * 7 = 84

Next, we multiply 2 by 3:

2 * 3 = 6

Finally, we subtract the second result from the first:

84 - 6 = 78

Therefore, the value of the expression 12a (2b) when a = 7 and b = 3 is 78.
