Simplifying Square Roots | Math with Mr. J

Math with Mr. J2 minutes read

Square roots can be simplified by identifying perfect square factors of the number and expressing them outside the square root symbol, such as 2 times the square root of 5 for the square root of 20. To simplify the square root of 32, the factors 16 and 2 or 4 and 8 can be used to achieve the final result of 4 times the square root of 2.
