Answer 1

Answer:

We have, 1989 be make perfect square.

442=1936<1989

442=1936<1989452=2025>1989

Let x be added or subtracted in 1989

Let x be added or subtracted in 1989Then,

x+442=1989

x+442=1989⇒x+1936=1989

x+442=1989⇒x+1936=1989⇒x=1989−1936

x+442=1989⇒x+1936=1989⇒x=1989−1936⇒x=53

"53 is subtracted from 1989 making perfect square."
