  2. Solving an equation, such as requires a new property………… Power Property of Equality: If a=b, then an=bn. But the new equation may have extraneous solutions

  3. You have to get the square root by itself before you can square it. NO SOLUTION A square root can never equal a negative #

  4. Change this problem
