Answer 1

Answer:

1/ [(3⁴) ^ 1/2] ⁻²

⇒  1 / [( 3 ²) ^ 1/2 ] ⁻²

=> 1/ (3)⁻²  =>   1* 9 = 9

36 ^ 7/2 - 36 ^ 9/2   / 36 ^ 5/ 2    

{ 36 can be writen as 6 ², hence after making 36 = 6 ² }

6 ^ 7/2 *2  - 6 ^ 9/2 * 2 /  36 ^ 5/2 *2

=>  6 ⁷ - 6 ⁹ / 6⁵

6 ⁷⁻⁹ / 6⁵        =>  6 ⁻²   / 6⁵  =>   6 ⁻²⁻ ⁵ =>    6 ⁻⁷   or 1/ 6 ⁷

Hope it helped
