The numbers in standard form are:
- 2.1 × 10⁻³
- 0.3 × 10⁶
- 1 × 10⁸⁰
- 157009
- 9.9999 × 10⁹⁹
- 0.99 × 10⁹
- 74 × 10⁻⁵
- 2 × 10⁷
- 4 × 10⁻⁸
- 12 × 10⁴
- 5.007 × 10³¹
The numbers not in standard form are:
- 0.004 × 10¹⁹ (coefficient < 1)
- 1800000 (not in scientific notation)
- 15 × 10⁹ (coefficient ≥ 10)
- 7.482 × 10¹⁰⁰ (coefficient > 10)
- 10⁵ × 10¹⁴ (two powers of 10 multiplied)
- 0.003 × 10²⁷ (coefficient < 1)
- 10³ × 10⁻⁸ (two powers of 10 multiplied)
- 1982073611 (not in scientific notation)
- 6 × 100⁴ (base not 10)
- 0.00040621 (not in scientific notation)
- 0.7 × 10¹³ (coefficient < 1)
- 4.5 × 20¹⁰ (base not 10)
- 48 × 10⁵⁵ (coefficient ≥ 10)
- 6.51192 × 10⁻⁵ (coefficient > 10)
- 0.0003 × 10⁴ (coefficient < 1)
- 8 × 11⁷ (base not 10)
Three numbers not in standard form and their standard form equivalents:
1. 0.004 × 10¹⁹ = 4 × 10¹⁶
2. 1800000 = 1.8 × 10⁶
3. 15 × 10⁹ = 1.5 × 10¹⁰
