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.
