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 )

(Product Rule: a^m × aⁿ = a^{m + n} , where ‘a’ is a real no. and m, n are positive integers.)

Now, taking 9^1/2 common, we get-
