Letter D) 7√x=14

Alan Ponce · Answer 2

It's 7√x = 14.

Step-by-step explanation:

That would be 7√x = 14.

In a radical equation the variable (x) is under a radical sign.

The equations x + √5 = 12 and 3 + x√7 = 13 contain radicals but they are radicals of a constant. The equation x^2 = 16 does not contain a radical.
