WHY IS IT NECESSARY TO CHANGE SOME RADICAL EXPRESSIONS INTO RATIONAL EXPONENTS AND HOW IS IT DONE?

jonathan5824 · Answer

WHY DOES SOLVING RADICAL EQUATIONS NEED A DIFFERENT PROCESS? HOW DO EXTRANEOUS SOLUTIONS ARISE FROM RADICAL EQUATIONS?

jonathan5824 · Answer

i said because you have to isolate the radical and see if the answer is true

natalief · Answer

An extraneous solution is a root of a transformed equation that is not a root of the original equation because it was excluded from the domain of the original equation.
