3 square root 16 plus 3 square root 128

The other tutor gave you a decimal approximation, but I think
you don't want that, but you want the simplest radical form.

3%2Asqrt%2816%29%2B3sqrt%28128%29

3%2A4%2B3%2Asqrt%2864%2A2%29

12%2B3%2Asqrt%2864%29sqrt%282%29

12%2B3%2A8%2Asqrt%282%29

12%2B24sqrt%282%29

A better decimal approximation is 45.9411255
