Given expression :
Using algebraic identity ( a + b )( a - b ) = a² - b² we get,
We know that : Law of exponents i. e ( a^m )^n = a^( mn ), So the expression becomes
Using law of exponent a^m × a^n = a^( m + n) we get,
Hence the value of the given expression is Option (a) x^( 2^n ) - y^( 2^n ).
Additional information :
Algebraic identity : An equation in wich every variable satisfies is said to be an algebraic identity.
E. g
- ( a + b )² = a² + b² + 2ab
- ( a - b )² = a² + b² - 2ab
- ( a + b )( a - b ) = a² - b²
- ( x + a )( x + b) = x² + ( a + b)x + ab
- ( a + b )² - ( a - b )² = 4ab
- ( a + b + c )² = a² + b² + c² + 2ab + 2bc + 2ca
