  2. It is a square root, not a cube root. and therefore we cannot cancel out the power of 3 of each number. And son we cannot cancel the power of 3.

  3. ^3 can not be covered by square roots as square roots cancels out ^2, but not ^3.

  4. Square root divides the power by 2. Not 3. IT'S A SQUUUAAARE. Not a cube root then the power is divided by 3.

  5. the ^3 cannot be cancelled away as it is square rooted, not cube rooted.

  6. it is a square root, not a cube root, so the ^3s cannot be cancelled away.
