Solve square root of (2x-4) is greater than 4.

[From: ] [author: ] [Date: 12-04-20] [Hit: ]
If root (2x-4) has to be 5 or more, it has to be even so 6 is the least value.6 squared is 36,and x=20-sqrt(2x-4)>4, first square both sides to yield: 2x-4>16, combine like terms: 2x >20,......
Solve square root of (2x-4) is greater than 4.

-
sqrt(2x-4) > 4 Square both sides

2x-4 > 16 Add 4 to both sides

2x > 20 Divide both sides by 2

x > 10

What about x=20?

If root (2x-4) has to be 5 or more, it has to be even so 6 is the least value.
6 squared is 36,
so if 2x-4=36
then 2x=40
and x=20

-
sqrt(2x-4)>4, first square both sides to yield: 2x-4>16, combine like terms: 2x >20, and divide by 2: x>10
