How to solve
Split the radicand into a perfect square times what is left; the square root of the perfect square comes outside.
Steps
- Find the largest perfect square dividing the radicand.
- Write √(k²·f) = k√f.
- Check that what stays inside has no square factor.
Example
Simplify √12.
- 12 = 4 · 3.
- √12 = √4 · √3 = 2√3.
Answer: 2sqrt(3)
How to type answers
- Use sqrt(n) for radicals, like 2sqrt(3)
