(a+b)3 - (a-b)3
= [ a3 + b3 +3a2b +3ab2] -[ a3 - b3 -3a2b +3ab2]
= a3 + b3 +3a2b +3ab2 - a3 + b3 +3a2b - 3ab2
= b3 +3a2b + b3 +3a2b
= 2b3 +6a2b

(2) 9.98 bar.
Since 9.98 bar. is a non-terminating and recurring (repeating) decimal.
So, it is a rational number.
(3) 169 = 13 * 13 = 132
So, 169 is a perfect square.
Thus, √169 is a rational number.
