Let us first resolve the given numbers into prime factors.

By prime factorization,


\longmapsto √8 = √( 2 × 2 × 2)


\longmapsto √8 = 2√2

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\longmapsto √98 = √( 2 × 7 × 7)


\longmapsto √98 = 7√2

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\longmapsto √32 = √( 2 × 2 × 2 × 2 × 2)


\longmapsto √32 = 2 × 2√2


\longmapsto √32 = 4√2

According to the question,


\longmapsto √8+√98+√32


\longmapsto 2√2 + 7√2 + 4√2

  • Taking √2 as common.


\longmapsto √2(2 + 7 + 4)


\longmapsto √2(13)


\longmapsto 13√2

So, we get that :

√8+√98+√32 → 13√2
