Chapter 2: Problem 3

Use the grouping symbols to help perform the following operations. $$4[2(11-5)]$$

Short Answer

Expert verified
Answer: 48

Step by step solution

01

Solving the operation within parentheses

Start by solving the expression within the parentheses: \((11-5)\). Subtract 5 from 11 to get 6: \(4[2(6)]\).
02

Solving the operation within the brackets

Now, we must perform the multiplication inside the brackets with the operation: \(2(6)\). Multiply 2 by 6 to get 12: \(4[12]\).
03

Perform the final multiplication

Lastly, we must perform the multiplication of the remaining expression: \(4[12]\). Multiply 4 by 12 to get the final result, which is 48: \(4 \cdot 12 = 48\). So, $$4[2(11-5)] = 48$$.
