What is the irrational cube root of ^3√81 rewritten as a product of an integer and another irrational cube root?

1 answer

The cube root of 81 is 4. So, we want to find an expression for the cube root of 81 as a product of an integer and an irrational cube root.

Since the cube root of 81 is 4, we can rewrite it as:

^3√81 = 4 * (^3√1) = 4 * 1 = 4

So, the irrational cube root of 81, ^3√81, can be rewritten as the product of an integer (4) and another irrational cube root (√1).
