Math radicals question

Answer 1

Let's find the factors of 32 and 72:

32=2*4*4 72=6*6*2
Therefore both of the radicals can be simplified into
`16 √(2)` and
`12 √(2)`. Now adding them we get
`28 √(2)`

Answer 2

4√32+2√72

4√(2*2*2*2*2)+2√(2*2*2*3*3)

4√(16*2)+2√(4*9*2) moving out all of the perfect squares...

4*4√2+2*2*3√2

16√2+12√2

(16+12)√2

28√2
