Answer 1

4root12 × 7root16
4×2root3 ×7×4
8root3×28
224root3 is answer obtained

Answer 2

first factorise 12=2x2x3 , then factorise 6=2x3

second, given  4√12 x 7√6 can be written as 4√2x2x3 * 7√2x3

and one more step , multiple like this 4x7√2x2x3x3x2

one 2 and one 3 comes out and one 2 is left inside root

4x7x2x3√2=168√2
