Explanation Given: The expression is ( x − 2 y ) 10 Key points used: The binomial theorem, ( a + b ) n = ( n 0 ) a n + ( n 1 ) a n − 1 b + ( n 2 ) a n − 2 b 2 + ... + ( n r ) a n − r b r + .... + ( n n ) b n Calculation: Consider the expression is ( x − 2 y ) 10 Using the binomial theorem, ( a + b ) n = ( n 0 ) a n + ( n 1 ) a n − 1 b + ( n 2 ) a n − 2 b 2 + ... + ( n r ) a n − r b r + .... + ( n n ) b n c n r = n ! r ! ( n − r ) ! In the expression ( x − 2 y ) 10 , a = x , b = − 2 y and n = 10 So, we can write ( x − 2 y ) 10 as
