Answer:
The square root of 38 cannot be simplified, so it is written as √38.
Step-by-step explanation:
To simplify a square root that is not a perfect square, factor the number. If any of its factors are perfect squares, it can be simplified.
For example, √50 can be simplified into √(25*2). 25 is a perfect square, so this can be further simplified into 5√2.
The factors of 38 are 1, 2, 19, and 38. As none of these numbers are perfect squares, √38 cannot be further simplified.
