here are the solutions to the math questions.

1.2.3 Complete the rule in symbols:

  • am÷an=am−na^m \div a^n = a^{\boxed{m-n}}
  • (am)n=am×n(a^m)^n = a^{\boxed{m \times n}}

1.3 Complete the following table by using your calculator. The first line has been done for you as an example.

1.3.2 Explain the general rule of what is happening in the table above in your own words.
When a power is raised to another power, the exponents are multiplied together, while the base remains the same.

1.3.3 Complete the rule in symbols:
(am)n=amn(a^m)^n = a^{\boxed{mn}}

1.3.4 Does this rule apply for every number in the bracket? (2×3)2×(3×2)2(2 \times 3)^2 \times (3 \times 2)^2? Show your workings.
Yes, the rule (am)n=amn(a^m)^n = a^{mn} applies to each factor within the bracket.

  1. Rewrite the expression using the rule (ab)n=anbn(ab)^n = a^n b^n.

    (2×3)2×(3×2)2=(21×31)2×(31×21)2(2 \times 3)^2 \times (3 \times 2)^2 = (2^1 \times 3^1)^2 \times (3^1 \times 2^1)^2
  2. Apply the rule (am)n=amn(a^m)^n = a^{mn} to each factor.

    =(21×2×31×2)×(31×2×21×2)= (2^{1 \times 2} \times 3^{1 \times 2}) \times (3^{1 \times 2} \times 2^{1 \times 2})
  3. Simplify the exponents and calculate the value.

    =(22×32)×(32×22)=(4×9)×(9×4)=36×36=1296= (2^2 \times 3^2) \times (3^2 \times 2^2) = (4 \times 9) \times (9 \times 4) = 36 \times 36 = 1296

    Answer: ✅ Yes, the rule applies to each factor within the bracket.

    1.3.5 Is (2×3)2×(3×2)2(2 \times 3)^2 \times (3 \times 2)^2 the same as (2×3×3×2)2(2 \times 3 \times 3 \times 2)^2? Show your workings.

  4. Calculate the value of the left-hand side (LHS).

    (2×3)2×(3×2)2=(6)2×(6)2=36×36=1296(2 \times 3)^2 \times (3 \times 2)^2 = (6)^2 \times (6)^2 = 36 \times 36 = 1296
  5. Calculate the value of the right-hand side (RHS).

    (2×3×3×2)2=(6×6)2=(36)2=1296(2 \times 3 \times 3 \times 2)^2 = (6 \times 6)^2 = (36)^2 = 1296
  6. Compare the LHS and RHS.

    Since 1296=12961296 = 1296, the expressions are the same.
    Answer: ✅ Yes, they are the same.

    ACTIVITY 2: FUNCTIONS AND RELATIONS

    2.1 Use the following rule: To find the y-values, add 3 to the x-values and then divide by 5.
    The rule can be written as y=x+35y = \frac{x+3}{5}.

    2.1.1 Complete the table of values.

    | xx | $y
