Step-by-step explanation:
49
50-1
We want to find 49^ 2 using the following identity
(x − y)^2 = x^2 − 2xy + y^2
Let x= 50 and y=1
(50-1) ^2 = 50^2 - 2 *50 *1 + 1^2
49^2 = 2500 - 100 +1
= 2400 +1
= 2401
a = 10 b= 13
a^3 + b^3 = (a + b)(a^2 − ab + b^2)
10^3 + 13^3 = ( 10+13) ( 10^2 - 10*13 + 13^2)
= (23) ( 100-130+169)
= 23 ( 139)
