Question

1. 100 - 3(2 + 1)^2

Explanation:

Step1: Calculate inside the parentheses

First, we solve the expression inside the parentheses: \(2 + 1 = 3\).

Step2: Calculate the exponent

Next, we calculate the exponent: \(3^2 = 9\).

Step3: Multiply

Then, we multiply \(3\) by \(9\): \(3\times9 = 27\).

Step4: Subtract

Finally, we subtract this result from \(100\): \(100 - 27 = 73\).

Answer:

\(73\)
