Rewrite ∛40 as a product of an integer and another irrational cube root
show work
To rewrite ∛40 as a product of an integer and another irrational cube root, we can factor 40 into its prime factors: 40 = 2 * 2 * 10.
Since there are two 2's in the prime factorization, we can take one of them outside of the cube root: ∛40 = ∛(2^2 * 10) = ∛(2^2) * ∛10 = 2 * ∛10.
