Question

49^2-1 evaluate after factorising

Answer 1

Answer:

2400

Step-by-step explanation:

49² - 1²

Using the identity a² - b² = (a + b) (a - b)

Here,

a = 49

b = 1

Therefore,

49² - 1²

= (49 + 1) (49 - 1)

= 50 X 48

= 2400

HOPE IT HELPS YOU

Answer 2

Answer:

2400 is your Answer......................

Now,49^2-1

=49^2-1^2

=(49+1)×(49-1)

=50×48

=2400
