(the fourth root of t plus 8)=(the fourth root of 2t)

Since both sides of the equation are "fourth root of", the stuff under the radical on each side are equal.

t + 8 = 2t
8 = t

to get rid of the fourth root multiply by the fourth power and you will end up with T + 8 = 2T subtract T from both sides for the equation and you will end up with T = 8

Is the 8 underneath the radical? If so,
since they're both the 4th root, take both sides to the fourth power to get rid of the radicals . That leaves you with :

t+8 = 2t
t= 8

(the fourth root of t plus 8)^4=(the fourth root of 2t)^4
t + 8 = 2t
8 = t

raise each side of the equation to the power of four. this will cancel the fourth roots out so you have:

t + 8=2t
subtract t from both sides

8=t ot t=8

yeah, raise both sides to the 4th power to get rid of the fourth roots so you're left with:
t+8=2t
subtract t on both sides:
t=8

(t+8)^1/4= (2t)^1/4 tmust be >=0
raising to the fourth power
t+8=2t so t=8

4^√t+8=4^√2t
Take both sides to the power of 4:
(4^√t+8)^4=(4^√2t)^4
t+8=2t
-t+8=0
-t=-8
t=8

Check:
4^√8+8=4^√2(8)
4^√16=4^√16
2=2

raise both sides to the 4th power to get rid of the fourth roots then you are left with
t+8=2t
subtract from both sides and........
t=8
