Solve this and show your work so that i can understand

(Look at image first before reading explanation!!)

Keeping in mind that this is all underneath the cube root:

Separate 6^4 to into (6^3)(6^1)

The cube root cancels the power of 3 on 6^3 therefore it can be moved outside of the radical.

As for 6^1, anything to the power of 1 is itself, so 6^1=6. Nothing else can be simplified so you are left with the answer in the image attached.

Hope this helps!

These are the multiples of 15 but what you are probably asking or what are the factors of 15
