Text Solution

AI Generated Solution

The correct Answer is:
To determine whether the statement \( 2\sqrt{4} + 2 = 6 \) is true or false, we can follow these steps: ### Step 1: Calculate \( \sqrt{4} \) The square root of 4 is calculated as follows: \[ \sqrt{4} = 2 \] ### Step 2: Substitute \( \sqrt{4} \) into the expression Now we substitute \( \sqrt{4} \) back into the original expression: \[ 2\sqrt{4} + 2 = 2 \times 2 + 2 \] ### Step 3: Perform the multiplication Next, we perform the multiplication: \[ 2 \times 2 = 4 \] ### Step 4: Add the result to 2 Now we add the result from the multiplication to 2: \[ 4 + 2 = 6 \] ### Step 5: Compare with the right-hand side Now we compare the left-hand side (LHS) with the right-hand side (RHS): \[ LHS = 6 \quad \text{and} \quad RHS = 6 \] Since both sides are equal, we conclude that the statement is true. ### Final Conclusion The statement \( 2\sqrt{4} + 2 = 6 \) is **True**. ---
