Section A

Question 1:

• a) Write 0.000437 in standard form. To write a number in standard form, we express it as a number between 1 and 10 multiplied by a power of 10. Move the decimal point 4 places to the right to get 4.37. Since we moved it to the right, the power of 10 is negative.

  $$0.000437 = 4.37 \times 10^{-4}$$
  • Answer: $\boxed{4.37 \times 10^{-4}}$

• b) Evaluate $3.
