Question

The cube root of 3 * the cube root of 9

Answer 1

3

Answer 2

could you explain?

Answer 3

yes....
\[\sqrt[3]{3}*\sqrt[3]{9} = \sqrt[3]{27} = 3\]

Answer 4

I thought you couldn't multiply radicals unless they have the same base?

Answer 5

nope... that's not the case... :)
as long as they are both cube roots... you can combine :)

you can't add them though.. you can multiply

Answer 6

ok thank you:) is it true that you can't multiply the fourth roots of 3 and -3? why is that if it follows what you said before?
