x = [গণিত] eq [গণিত] ( ¾ ¾ , c + b) (a + b c); x এর মান 1 হবে যখন -

ক. a = 0, b = 0, c = 0

খ. a = 1, b = 0, c = 0

গ. a = 1, b = 1, c = 0

ঘ. a = 0 , b = 1, c = 1

উত্তর: a = 1, b = 0, c = 0

ব্যাখ্যা: a = 0, b = 0, c = 0 হলে, x = [গণিত] eq [গণিত] ( ¾ ¾ ,c + b) (a + bc) = [গণিত] eq [গণিত] ( ¾ ¾ ,0 + 0) (0 + 0.0) = [গণিত] eq [গণিত] ( - ,0) (0 + 0) = 1.0 = 0 a = 1, b = 0, c = 0 হলে, x = [গণিত] (a + bc) = [গণিত] eq [গণিত] ( ¾ ¾ ,0 + 0) (1 + 0.0) = [গণিত] eq [গণিত] ( - ,0) . 1 = 1 . 1 = 1 a = 1, b = 1, c = 0 হলে, x = [গণিত] eq [গণিত] ( ¾ ¾ ,c + b) (a + bc) [গণিত] eq [গণিত] ( ¾ ¾ ,0 + 1) (1 + 1.0) = [গণিত] eq [গণিত] ( - ,1) (1 + 0) = 0.1 = 0 a = 0, b = 1, c = 1 হলে, x = [গণিত] eq [গণিত] ( ¾ ¾ ,c + b) (a + bc) [গণিত] (0 + 1.1) = [গণিত] eq [গণিত] ( - ,1) (0 + 1) = 0.1 = 0 অর্থাৎ a = 1, b = 0, c = 0 হলে x এর মান 1 হবে।
