Answer:

Option A:

A. Each side of 5√x = 10 should be squared.

(5√x)^2 = 10^2

25x = 100, so x = 4

B. x = -6 is an extraneous solution, so x = 2 is the only solution. When solving equations with radicals, you need to check for extraneous solutions.

Option B:


√(2x) + 5 = 1

does not have any real solutions.


\sqrt[4]{m + 4} - \sqrt[4]{3m} = 0


\sqrt[4]{m + 4} = \sqrt[4]{3m}


m + 4 = 3m


2m = 4


m = 2
