assuming expression is
5√12 + 2√2 + (2√2 / 5)
5(√4 times √3) + 2√2 + [2√2 / 5]
10√3 + 2√2 + (2√2)/5
(50√3 + 10√2 + 2√2) / 5
(50√3 + 12√2) / 5
2 (25√3 + 6√2) / 5
you need to make sure you put in brackets so that you can define where the divisions are!

5√12 + 2√2 + 2√2 / 5
= 5√4√3 + 2√2 + (2/5)√2
= 5(2)√3 + 2√2 + (2/5)√2
= 10√3 + (2 + 2/5)√2
= 10√3 + (10/5 + 2/5)√2
= 10√3 + (12/5)√2 <----answer
= 5√4√3 + 2√2 + (2/5)√2
= 5(2)√3 + 2√2 + (2/5)√2
= 10√3 + (2 + 2/5)√2
= 10√3 + (10/5 + 2/5)√2
= 10√3 + (12/5)√2 <----answer
