She wishes everything were simplified. So even though sometimes things like the inside

In the case of radicals, simplifying means to find another expression with the same value,
- 00:29
not to find a decimal approximation of the radical.
- 00:33
We start by finding any two factors of 54, numbers that can divide 54 and leave a remainder

of zero. Say...9 and 6. Then continue simplifying until we're only left with prime factors.
- 00:51
We can factor 9 into 3 and 3...and 6 by 3 and 2. No one likes to be lonely...so let's
- 01:07
pair up repeated numbers and take them out of the radical...3 and 3 pair up...and we're
- 01:16
left with 3 and 2. Since they don't have any potential partners, we can just multiply the
- 01:31
numbers back togetherÉ Éleaving us with 3 root 6.
