What would be the root index if the following expression were written in radical form? 12x^2/3

• The implied root index

• 2

• There is no root index..

• 3

• Subtract 6 from both sides

• Square both sides

• Subtract 94 from both sides

• Divide both sides by 5

• -6

• Divide both sides by 6

• 3

• Square root both sides

• 61.2

• -91.6
