Hey there!


  • \bold{ -5x^3=625}
  • Firstly, we have to
    \bold{divide} by

    \bold{-5}

  • \bold{Like:(-5x^3)/(-5)=(625)/(-5)}

  • \bold{Cancel:(5x^3)/(-5)}

  • \bold{(625)/(-5)} because it helps us solve for our answer
  • We get:
    \bold{x^3=-125}
  • Take out the cubic root (
    \bold{x^3})

  • \bold{x=(-125)^(1)/(3)}
  • Solve that
    \uparrow

  • \boxed{\boxed{\bold{Answer:x=-5}}}
    \checkmark

Good luck on your assignment and enjoy your day!
