This should be a quick head calculation, left-to-right, realizing that dividing by (1/81) is the same as multiply by 81, yields (81^3)^(1/2) = 9^3 = 729.
This question is poorly stated, because division is not associative. Depending on the order of operation, a/b/c could be either (a/b)/c=a/(bxc) or a/(b/c)=(axc)/b.

729 final answer

I got 729 as the solution to the problem as you need to get the root of 531441 and 729^2 equals 531441.

Sqrt[(1/81)÷(1/81)÷(1/81)÷(1/81)÷(1/81)]=729

No, division and multiplication is always left to right. There are no brackets there, so don't add them in random places.
@@MWal-x5x Not the way I learned it, not left to right unless specified by parenthesis.
@@nathanmattor401 So unfortunately you learned it wrong. But don't worry, it's never too late to learn new things :)

√（1×81³）=√（3¹²）=3⁶=729
2:15 =1×(81/1)×(81/1)×(81/1)
=vʼ(81×82×81) ??? 😳 😯 😬
