Example 3 Verify ( 30) [13 + ( 3)] = [( 30) 13] + [( 30) ( 3)] ( 30) [13 + ( 3)] = [( 30) 13] + [( 30) ( 3)] LHS 30 [13 + ( 3)] = 30 [13 3] = 30 10 = 300 RHS [( 30) 13] + [( 30) ( 3)] = [ 3 10 13] + (30 3) = [ 3 13 10] + [90] = ( 39 10) + 90 = 390 + 90 = (390 90) = 300 Since LHS = RHS Hence verified
