Standard Form questions students ask
What is standard form?
Standard form (scientific notation) writes numbers as a × 10ⁿ where a is between 1 and 10. E.g. 3,400,000 = 3.4 × 10⁶.
How do I multiply numbers in standard form?
Multiply the coefficients together and add the powers of 10. E.g. (2 × 10³) × (4 × 10²) = 8 × 10⁵.
