Question

evaluate.
a. 2(50 - 4·3²)

Explanation:

Step1: Calculate the exponent

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

Step2: Perform the multiplication

Next, we do the multiplication inside the parentheses: \(4\times9 = 36\).

Step3: Perform the subtraction

Then, we subtract the result from 50: \(50 - 36 = 14\).

Step4: Perform the final multiplication

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

Answer:

28
