Laws of indices (exponents)

Answers and reasoning. Review before teaching.

  1. 1. Simplify x^5 × x^6 in the form x^n.

    x^11

    When multiplying powers with the same base, add the exponents: 5 + 6 = 11, giving x^11.

  2. 2. Simplify x^4 × x^11 in the form x^n.

    x^15

    When multiplying powers with the same base, add the exponents: 4 + 11 = 15, giving x^15.

  3. 3. Simplify x^15 ÷ x^4 in the form x^n.

    x^11

    When dividing powers with the same base, subtract the exponents: 15 − 4 = 11, giving x^11.

  4. 4. Simplify x^11 ÷ x^5 in the form x^n.

    x^6

    When dividing powers with the same base, subtract the exponents: 11 − 5 = 6, giving x^6.

  5. 5. Simplify x^3 × x^3 in the form x^n.

    x^6

    When multiplying powers with the same base, add the exponents: 3 + 3 = 6, giving x^6.

  6. 6. Simplify x^4 ÷ x^3 in the form x^n.

    x^1

    When dividing powers with the same base, subtract the exponents: 4 − 3 = 1, giving x^1.

  7. 7. Simplify x^7 ÷ x^3 in the form x^n.

    x^4

    When dividing powers with the same base, subtract the exponents: 7 − 3 = 4, giving x^4.

  8. 8. Simplify x^11 × x^9 in the form x^n.

    x^20

    When multiplying powers with the same base, add the exponents: 11 + 9 = 20, giving x^20.

  9. 9. Simplify x^8 × x^3 in the form x^n.

    x^11

    When multiplying powers with the same base, add the exponents: 8 + 3 = 11, giving x^11.

  10. 10. Simplify x^17 ÷ x^9 in the form x^n.

    x^8

    When dividing powers with the same base, subtract the exponents: 17 − 9 = 8, giving x^8.

  11. 11. Simplify x^20 ÷ x^8 in the form x^n.

    x^12

    When dividing powers with the same base, subtract the exponents: 20 − 8 = 12, giving x^12.

  12. 12. Simplify x^7 × x^11 in the form x^n.

    x^18

    When multiplying powers with the same base, add the exponents: 7 + 11 = 18, giving x^18.
