Answer 2

Step-by-step explanation:

• Identify the squares of odd

number :

i) 36 = √(2 × 2 × 3 × 3) = 2 × 3 = 6

ii) 49 =√ (7 × 7) = 7

iii) 529 =√(23 × 23) = 23

iv) 1681 = √(41 × 41) = 41

v) 2116 = √(2 × 2 × 23 × 23) = 2 × 23 = 46

vi) 196 = √(2 × 2 × 7 × 7) = 14

Hence,

From the above solutions, we get,

49, 529, 1681, are squares of odd
