Question

evaluate.
a. 2(50 - 4·3)

Explanation:

Step1: Calculate the exponent

First, we need to calculate \(3^2\). By the definition of exponentiation, \(3^2 = 3\times3 = 9\).

Step2: Perform the multiplication

Next, calculate \(4\times9\). \(4\times9 = 36\).

Step3: Perform the subtraction

Then, calculate \(50 - 36\). \(50 - 36 = 14\).

Step4: Perform the final multiplication

Finally, multiply the result by 2. \(2\times14 = 28\).

Answer:

28
