Best answer
`2**3 = 2^(3 )= 8 ` तथा `3 ** 2 = 3 ^(2 )=9 `
`therefore 2 **3 ne 3 ** 2`
अतः `**`, समुच्चय N पर क्रमविनिमेय नहीं है।
साथ ही `2**(2**3)=2**2^(3)=2**8=2^(8)=256`
तथा `(2**2)**3=2^(2)**3=4**3=4^(3)=64`
स्पष्टतः `2**(2**3)^(1)(2**2)**3`
अतः `**`, समुच्चय N पर साहचर्य नहीं है।
अतः `**`, समुच्चय N पर न तो क्रमविनिमेय है और न साहचर्य है।
