Answer 1

196 is a square if a even number i.e 14

Answer 2

196 is the square of an even number. (Option a)

• When we obtain a number's square, the square's value cannot end with 2, 7, 3, or 8.
• Of the numbers given, 196 are 14's square, 441 are 21's.
• Similarly on squaring 25, we get 625 and on squaring 23, we get 529.
• The only number that is even from 14, 21, 25, and 23 is 14.
• So, option a is correct and an even number's square.
