Question

how do i simplify this, assuming all variables are real numbers? ³√64(x-8)³

(the radical sign extends over the whole equation)

Answer 1

\(\Large \sqrt[3] {64 \cdot (x-8)^3}=\sqrt[3] {64} \cdot \sqrt[3] {(x-8)^3}=4(x-8) \)

Answer 2

Thank you. And, how did you get the mathematical symbols?

Answer 3

right-click on the symbols themselves and choose "Show math as" --> "tex commands".
it's like entering equations using the blue "Equation" button on the left side of this reply box.
