Simplify the square root of 50.
Answer and explanation
Correct answer: D. 5 root 2
- Step 1: Write 50 as 25 x 2, where 25 is a perfect square. Step 2. Take root 25 = 5 outside the root sign. Answer: 5 root 2. Why not the others: 25 root 2 forgets to square-root 25; 2 root 5 swaps the numbers (that equals the root of 20); 10 root 5 is the root of 500.
