Problem 3 - Elementary Algebra

Question

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

Step-by-Step Solution

Answer

Answer: 48

Step 1: Solving the operation within parentheses

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

Step 2: 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: \(4[12]\).

Step 3: 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, $$4[2(11-5)] = 48$$.
