Detailed explanation-1: -√48 = √(2)2. √(2)2 √3. √48 = 4√3. Therefore, the square root of 48 in radical form is 4√3.
Detailed explanation-2: -To simplify an expression containing a square root, we find the factors of the number and group them into pairs. For example, a number 16 has 4 copies of factors, so we take a number two from each pair and put it in front of the radical, finally dropped, i.e., √16 = √(2 x 2 x 2 x 2) = 4.
Detailed explanation-3: -The square root of negative 48 is equal to 4i√(3). This may leave you wondering what that i in there is! The number i is an imaginary number with a value of √(-1). We use this number to deal with square roots of negative numbers.
Detailed explanation-4: -The value of the cube root of 48 rounded to 5 decimal places is 3.63424. It is the real solution of the equation x3 = 48.
