Little question on multiplying radicals

Hi,

I have the following to multiply :

secondroot(d)*thirdroot(ab)

I have the following answer : thirdroot(a^2*b^2*d^3)


I think that the answer is an error

Here's my answer : thirdroot(abd*d^1/2)

Thank you

hi Al-Allo

I agree with you.  The other answer is the square of the given amount.
