Final answer:
To simplify the square root of 105, we find the largest perfect square factor of 105, which is 9. Then we simplify further to get 3 times the square root of 11.
Step-by-step explanation:
To simplify √105, we need to find the largest perfect square that is a factor of 105. The largest perfect square factor of 105 is 9 (since 9 is the largest perfect square that is less than 105). Therefore, we can write √105 = √(9 × 11).
Using the property that √(a × b) = √a × √b, we can simplify further: √105 = √9 × √11.
The square root of 9 is 3, so the simplified form of √105 is 3√11.
