subtracting radical expressions

[Gr8fu13]

I had to come up with a radical expression. This is what I wrote:
³?64 - ³?27
Would the answer be 1?
Or would this expression be unsolvable. I cannot find any examples that contain only an index for subtraction. Thanks!

Yes, that is correct.

The cube root of 64 is 4. The cube root of 27 is 3.

4-3=1.

Thank you so much for confirming that! :wink:
