Given
625 - 49 = 576 .
625 = 25^2
49 = 7^2.
25^2 - 7^2
( a^2 - b^2 = a+b x a-b )
Using formula --
a = 25 . b = 7
(25+7) (25-7)
32 x 18.
= 576.
Hence , 625 - 49 = 576.
625 - 49 = 576 .
625 = 25^2
49 = 7^2.
25^2 - 7^2
( a^2 - b^2 = a+b x a-b )
Using formula --
a = 25 . b = 7
(25+7) (25-7)
32 x 18.
= 576.
Hence , 625 - 49 = 576.
