48 is not a perfect square. We can find the square root of 48 by the approximation method. For the accurate value, we can use the long division method. In the approximation method, we find square numbers close to 48. We see that 36 and 49 are the perfect square numbers close to 48. The square root of 36 is 6 and the square root of 49 is 7. Therefore the square root of 48 must lie between 6 and 7 and more close to 7 as 48 is closer to 49. This method only gives us an approximate answer. To know the exact value we can use the long division method and find a more accurate decimal value for √48.
Simplified Radical Form of Square Root of 48
48 is a composite number. When we find square root of any number, we take one number from each pair of the same numbers from its prime factorization and we multiply them. The factorization of 48 is 2 × 3 × 2 × 2 × 2 which has 1 pair of the same number. It can also be written as 48 = 24 × 31. Thus, the simplest radical form of √48 is 4√3 itself.
Let us follow the steps to find the square root of 48 by long division.
Step 1: Starting from the right, we will pair up the digits by putting a bar above them.Step 2: Find a number which, when multiplied to itself, gives the product less than or equal to 48. So, the number is 4. Putting the divisor as 6, we get the quotient as 6 and the remainder 36.Step 3: Now double the divisor. Guess the largest possible digit which will also become the new digit in the quotient, such that when the new divisor is multiplied to the new quotient the product is less than or equal to the dividend. Divide and write the remainder.

Solution
We need to express 48 as the product of its prime factors as 48 = 2 × 3 × 2 × 2 × 2.Therefore, √48 = √(2 × 2 × 2 × 2 × 2) = 4√3.Thus, 4√3 is in the lowest radical form.
