n Let we have x

-n n Then x is the reciprocal of x

n 1 i.e 1 × x = ------- -n x

Its mean multiplication of x^n and its reciprocal x^-n is same as dividing x^n by x^n

n n -n x i.e x × x = ------ ........(i) n x

Its mean multiplication of x^-n and its reciprocal x^n is same as dividing x^n by x^n

n -n n x i.e x × x = ------........(ii) n x

From (i) & (ii) n -n n n -n x x × x = x × x = ------ n x
