Radical means square root, so
3 radical 16 = 3%2Asqrt%2816%29
The square root of 16 is either 4 or -4.
Thus 3%2Asqrt%2816%29+=+3%2A4+=+12
or 3%2Asqrt%2816%29+=+3%2A-4+=+-12

"Radical" doesn't necessarily mean square root. A radical is a surd, so the index may not necessarily be 2.
3 radical 16 might mean root%283%2C16%29+=+root%283%2C+8%2A2%29+=+2root%283%2C2%29.
