This problem asks us to reduce a radical expression of the fourth root of 64, m to the eighth, end to the four.
00:13
So because the fourth root is even, we just have to be careful.
00:17
So like when the fourth root cancels out with end to the fourth, it's going to leave us with the absolute value of n, because n could sometimes be negative.
00:24
So there's that.
00:28
So we're going to break this down into three parts.
00:31
So we have the fourth root of 64.
00:34
We have the fourth root of m to the eighth.
00:39
And we have the fourth root of end to the fourth.
00:43
Okay.
00:43
So each one of these is going to show us something different.
00:46
So fourth root of end to the fourth.
00:50
That's just going to be the absolute value of n.
00:52
So the fours cancel out.
00:54
We have four to the one fourth power.
00:56
So it's just end to the first...
