Add polynomials to find perimeter

Add polynomials to find perimeter

What you'll learn

  • Identify the base and exponent in expressions with fractional bases (e.g., (1/2)^3) with 80% accuracy.
  • Calculate the value of expressions with fractional bases and whole number exponents (e.g., (2/3)^2) and express the answer as a simplified fraction in at least 7 out of 10 attempts.
  • Explain, in their own words, why a fractional base raised to a power results in a smaller number (or a number closer to zero) in at least 2 out of 3 opportunities.
  • Solve real-world problems involving exponents with fractional bases, such as calculating the area of a square with sides of length 1/4 meter, with at least 75% accuracy.
