To rewrite the irrational cube root ∛40, we can break it down into its prime factors. The prime factorization of 40 is 2^3 x 5. Therefore, we can rewrite the cube root as:
∛40 = ∛(2^3 x 5)
Taking out the perfect cube factor, we have:
∛40 = ∛(2^3 x 5) = 2∛5
So, the irrational cube root ∛40 can be rewritten as the product of the integer 2 and the irrational cube root ∛5.

6 answers
the options are
A. 2 3√5
B. 2 3√10
C.-2 3√5
D. 8 3√5
A. 2 3√5
B. 2 3√10
C.-2 3√5
D. 8 3√5
To find the correct answer, we need to simplify further.
The cube root of 5 is an irrational number because 5 is not a perfect cube. Therefore, we can rewrite the irrational cube root as:
∛5 = 3√5
Now, we can rewrite ∛40 as a product of an integer and another irrational cube root:
∛40 = 2∛5
Thus, the correct answer is A. 2 3√5.
The cube root of 5 is an irrational number because 5 is not a perfect cube. Therefore, we can rewrite the irrational cube root as:
∛5 = 3√5
Now, we can rewrite ∛40 as a product of an integer and another irrational cube root:
∛40 = 2∛5
Thus, the correct answer is A. 2 3√5.
