Question 1 :

Using the prime factorization method, find which of the following numbers are perfect squares:

 (i)   441
(ii)   576
(iii)  11025

Formulae used :

Distance Formula to find distance between two points (x1,y1) and (x2,y2) is :             D = √[(x2 – x1)2 + (y2 – y1)2 ]

Solution :

Sol. (i) Here x1 = 2, y1 = 3, x2 = 4 and y2 = 1
         ∴ The required distance
