കണക്കുകൂട്ടല്‍:

ഭിന്നക സംഖ്യ - p/q രൂപത്തിലുള്ള ഒരു സംഖ്യ.

നൽകിയിരിക്കുന്ന ഓപ്ഷൻ അനുസരിച്ച്

\(\sqrt {{3^2} + {4^2}} \) = √25 = 5 ഒരു ഭിന്നക സംഖ്യയാണ്.

\( √ {12.96} \) = 3.6 ഒരു ഭിന്നക സംഖ്യയാണ്

⇒ √125 = 5√5 ഒരു ഭിന്നക സംഖ്യയല്ല.

⇒ √900 = 30 ഒരു ഭിന്നക സംഖ്യയാണ്.

∴ √125 ഒരു ഭിന്നക  സംഖ്യയല്ല.
