Add and subtract polynomials using algebra tiles

Add and subtract polynomials using algebra tiles

What you'll learn

  • Identify the missing base or exponent in equations involving powers of whole numbers with at least 80% accuracy.
  • Solve for the missing exponent when given the base and the result of an exponential expression, demonstrating the correct steps in at least 3 out of 4 attempts.
  • Explain the relationship between exponents and bases in their own words, providing at least two examples of how changing the base or exponent affects the value of the expression, as assessed through a short written response.
  • Apply the concept of inverse operations (roots) to find the missing base when given the exponent and the result of an exponential expression in at least 75% of practice problems.
