Question

did I do this right? (³√-125)³ simplifies to -125? or is that only if the second ^3 is inside ( )

Answer 1

no you are correct

Answer 2

the cube root of -125 is -5 because -5 cubed is -125

Answer 3

oh that makes sense.

Answer 4

yea it simplifies only in -125
\[(\sqrt[n]{x})^n=x\]

Answer 5

oh yes of course. i did not see the "cubed" part. you get what you started with
good work!

Answer 6

\[\sqrt[3]{(-5)^3}=-5=> (-5)^3=-125\]
