Answer 1

Avery Alexander

#-5/6#

#root(3)(8/27) - 3/2#

#=> root(3)(2^3/3^3) - 3/2#

#=> 2/3 - 3/2#

#=> (2(2) - 3(3))/6#

#=> (4 - 9)/6#

#=> -5/6#

To calculate (\sqrt[3]{\frac{8}{27}} - \frac{3}{2}), first simplify the expression inside the cube root, which is (\frac{2}{3}). Then, subtract (\frac{3}{2}) from (\frac{2}{3}) to get the final result, which is approximately (-\frac{7}{6}).
