We know, √729 = 27
⇒ √7.29 = √(729/100) = 27/10 = 2.7
⇒ √72.9 = √(7.29 × 10) = 2.7 × √10 = 2.7 × 3.16 = 8.53
∴ √729 + √72.9 + √7.29 = 27 + 8.53 + 2.7 = 38.23
⇒ √7.29 = √(729/100) = 27/10 = 2.7
⇒ √72.9 = √(7.29 × 10) = 2.7 × √10 = 2.7 × 3.16 = 8.53
∴ √729 + √72.9 + √7.29 = 27 + 8.53 + 2.7 = 38.23

√729+√72.9+√7.29
27+8.53+2.7=38.23
27+8.53+2.7=38.23
