Yes
Because its square root is an irrational number
Yes, the square root of 48 is an irrational number. This is because 48 can be simplified to (4 \times 12), and since the square root of 4 is a whole number (2), we can express (\sqrt{48}) as (2\sqrt{12}). The square root of 12, however, is not a perfect square and cannot be simplified to a whole number, making (\sqrt{48}) irrational.
The square root of 48 is not an integer which means a whole number.
The square root of 48 can be written as 48 with a square root sign over it, 48 to the 1/2 power, a decimal equivalent (6.92...), or simplified as 4 square-roots of 3.
