√ 5 మరియు √ 7

భావన

అకరణీయ సంఖ్యలు అనేవి ముగిసే, ముగించని లేదా పునరావృతమయ్యే సంఖ్యలు.

గణన

√5 = 2.33 మరియు √7 = 2.64

అకరణీయ సంఖ్య 2.33... మరియు 2.64 మధ్య ఉంటుంది...

కాబట్టి, \(2{2\over5}\) మాత్రమే 2.33 మరియు 2.64 మధ్య ఉండే సంఖ్య

\(2{2\over5}\) అనేది \(\sqrt{5}\) మరియు \(\sqrt{7}\) మధ్య ఉండే అకరణీయ సంఖ్య
