Answer 1

To rewrite the irrational cube root 189√3 as the product of an integer and another irrational cube root, we can simplify the cube root of 189.

Let's write 189 as 27 * 7. Therefore, we can express the cube root of 189 as:

∛189 = ∛(27 * 7) = ∛27 * ∛7 = 3√7

So we have ∛189 = 3√7

Therefore, the irrational cube root ∛189 can be expressed as the product: 3 * √7
