The solution set of radical(x - 1) (is greater than sign) 5 is the set of all real numbers x such that:

F. x (is greater than sign) 4
G. x (is greater than sign) 6
H. x (is greater than sign) 24
J. x (is greater than sign) 25
K. x (is greater than sign) 26

">" symbol is done with period key and shift.

(x-1) > 5

Add one to both sides.

That leaves me with x > 6

To find the solution set of the inequality radical(x - 1) > 5, we need to isolate x.

First, we square both sides of the inequality to remove the radical sign:
(radical(x - 1))^2 > (5)^2
x - 1 > 25
x > 26

So, the solution set of the given inequality is x > 26.

The correct answer choice is therefore option K. x > 26.
