Answer:
A, B, and E apply
Step-by-step explanation:
One thing we can do is to make everything in the same format, under one square root, with no non-square roots.
First, we can say that 6 is equal to β36 as 6Β² =36, and 6 β₯ 0. Therefore, 6β3 = β36 * β3 = β108
For A, β3 * β36 = β108, so this applies
For B, β18 * β6 = β108, so this applies
For C, 108Β² = βsomething bigger than 108 = β11664, so this does not apply
For D, β54 β β108, so this does not apply
For E, β108 = β108, so this applies
For F, β3 * β6 = β18, so this does not apply
