Simplify:

(∵ Number with zero exponent rule: If ‘a’ is a rational no. other than zero, then a⁰ = 1)

(∵ Reciprocal law: If ‘a’ is a real no. and m is a positive integer, then )

where b≠0, a and b are real numbers, m is an integer)

where ‘a’ is a non-zero real no. and m, n are positive integers.)
