Algebra 2 Lsn 6-3

  1. 1. Solving Power Equations Power Equation ‐ When the variable is raised to a power Steps to Solve Power Equations: 1. Isolate the variable 2. Raise both sides of equation to reciprocal of power 3. Simplify and solve 4. Check for extraneous solutions 1
  2. 2. Review! Example 1:  Check 2
  3. 3. Example 2: Check 3
  4. 4. Example 3: Check 4
  5. 5. Example 4: Check 5
  6. 6. Example 5: Check 6
  7. 7. Example 6: Check 7
  8. 8. Example 8: Check 8
  9. 9. You can use a graphing calculator to check for solutions. 1. Let Y1 = left side and Y2 = right side.   2. Graph the equations. 3. Find all possible solutions using the intersection.  (Find where Y1  = Y2.) 9
