1. 7√7 + 4√7 - √7
= 7√7 + 4√7 - 1√7
= (7 + 4 - 1) √7
= 10√7 atau 26,4575131
2. √5 - 6√5 + 7√5
= 1√5 - 6√5 + 7√5
= (1 - 6 + 7) √5
= 2√5 atau 4,47213595
3. 3√2 + 4√8 + 7√32
= 3√2 + 8√2 + 7×2²√2
= 3√2 + 8√2 + 7×4√2
= 3√2 + 8√2 + 28√2
= 39√2 atau 55,1543289
4. 6√27 - 3√12 - √3
= 18√3 - 6√3 - √3
= 11√3 atau 19,0525589
