Simplify (36/81) raised to the power -1/2
rosijanka [135]

Step-by-step explanation:

Hey, there!!

I hope you mean,

\frac{ - 1}{2}  \: means \:  \sqrt{}

and

36 =  {6}^{2}  \: and \: 81 =  {9}^{2}

so \: \:  \sqrt{ \frac{ {6}^{2} }{ {9}^{2} } }

or \: (  { \frac{ {6}^{2} }{ {9}^{2} }) }^{ \frac{ - 1}{2} }

so, the answer is 6/9 or, 2/3.
