    • b)3.27 x 103 = 3270
    • c)4.32 / 104 = 0.000432
    • Powers that are positive go ↷. Powers that are negative go ↶.
  2. Write the following numbers in Standard form:

    A) 0.000621
    B) 473000
    C) 6000000
    D) 7.4
    E) 5720

    (this multiple choice question has been scrambled)
  3. Calculate: 
    (a)(3 × 106) × (4 × 103)
    (b)(6 × 107) ÷ (5 × 10-2)
    • a) (3 × 4) × (106 × 103) = 12 × 109 = 12000000000
    • b) (6x5) ÷ (10x 10-2) = 30 ÷ 105 = 0.0003
