Question 604073
Both the tutor and the program are correct, {{{-3*sqrt(-1000)=-30i*sqrt(10)}}}


So there must be a typo somewhere or the teacher is referencing a different problem maybe.


-------------------------------------------------------


If the problem is {{{-root(3,-1000)}}} (the negative cube root of -1000), which is completely different, then...



{{{-root(3,-1000)}}}


{{{-root(3,(-10)^3)}}}


{{{-(-10)}}}


{{{10}}}


So {{{-root(3,-1000)=10}}}
