Question 1189436
<br>
(1) Why be cute and say "tesseract root" instead of "fourth root".  Do you advocate coming up with obscure names for fifth, sixth, ..., and eighty-first roots?<br>
(2) Written in words, the expression is ambiguous.  Is it<br>
(square root of 64) times the (tesseract root of 128)^3<br>
or<br>
square root of (64 times the (tesseract root of 128)^3)<br>
or it could even be<br>
(square root of (64 times the (tesseract root of 128)))^3<br>
Re-post, making it clear what the expression is.<br>
Or, if you want to dare trying to work the problem yourself, instead of asking us to do your work for you, note that 64 = 4^3 and 128 = 4^(7/2)....<br>
