Multiply two monomials

LET’S TRY ONE

Simplify (2x2)(3x3).

6x5

Multiply the coefficients: 2 × 3 = 6. Add exponents of x: 2+3 = 5. The product is 6x5.

Learning steps & teaching tips

Multiply coefficients and use the product rule for exponents.

  1. Keep coefficient multiplication separate from adding exponents.
  2. Work through the example and explain why each operation is used.
  3. Estimate or use another method to check the result before choosing.

Try it together

Work with a partner: solve one example, explain the method, then change one number and predict what changes.

Keep coefficient multiplication separate from adding exponents.
