Why: Powers of 10 underpin scientific notation and SI units. 10⁶ = 1 million, 10⁻⁹ = 1 nanosecond. Scale from atoms to galaxies.

How: 10^n = 1×10×...×10 (n times) for n>0. 10^(-n)=1/10^n. SI: kilo=10³, mega=10⁶, giga=10⁹; milli=10⁻³, micro=10⁻⁶.

10⁻ⁿ = 1/10ⁿ

— Negative exponent

📋 Key Takeaways

  • • 10^n: Positive n = 1 followed by n zeros; negative n = 1/10^|n|
  • • 10^0 = 1. Any nonzero number to the power of 0 equals 1
  • • Scientific notation: a × 10^b where 1 ≤ |a| < 10
  • • SI prefixes: kilo (10³), mega (10⁶), milli (10⁻³), micro (10⁻⁶)
  • • Metric system uses powers of 10 for unit conversion

📖 How It Works

Powers of 10 are fundamental in science and engineering. 10^n means 10 multiplied by itself n times (n > 0), or 1 divided by 10^|n| (n < 0). SI prefixes map exponents to names: kilo=10³, mega=10⁶, milli=10⁻³, micro=10⁻⁶, etc.

Scientific notation writes numbers as a × 10^b where 1 ≤ |a| < 10. This compact form handles very large (e.g., 6×10²³) and very small (e.g., 1.6×10⁻¹⁹) values.

📝 Worked Example: 10³

Step 1: 10³ = 10 × 10 × 10

Step 2: 10 × 10 = 100, 100 × 10 = 1000

Result: 10³ = 1000 (one thousand)

SI prefix: kilo (k) = 10³

🚀 Real-World Applications

📐 Metric System

km, kg, mL — all use powers of 10. 1 km = 10³ m.

🔬 Science

Avogadro 6×10²³, electron 1.6×10⁻¹⁹ C.

💻 Computing

Storage: KB, MB, GB. Frequencies: MHz, GHz.

📊 Finance

Millions, billions, trillions. Market caps.

🌍 Earth Science

Earth mass ~6×10²⁴ kg. Distances in light-years.

⚡ Physics

Planck scale 10⁻³⁵ m. Universe age ~10¹⁰ years.

⚠️ Common Mistakes to Avoid

  • 10^3 ≠ 30: 10^3 = 1000, not 10×3. Exponent means repeated multiplication.
  • 10^(-2) ≠ -100: 10^(-2) = 1/100 = 0.01. Negative exponent = reciprocal.
  • Scientific notation: 35 × 10³ should be 3.5 × 10⁴ (1 ≤ |a| < 10).
  • Kilo vs kibi: 1 KB = 1024 bytes (binary); 1 kB = 1000 bytes (decimal).
  • Exponent limits: JavaScript limits ~±308. Beyond: Infinity or 0.

🎯 Expert Tips

💡 Use Scientific Notation

For very large or small numbers: 6.02×10²³ is easier than 602000000000000000000000.

💡 SI Prefixes

1 km = 1000 m. 1 mg = 0.001 g. Simplifies unit conversion.

💡 Product Rule

10^a × 10^b = 10^(a+b). 10^a ÷ 10^b = 10^(a-b).

💡 Decimal Exponents

10^0.5 = √10 ≈ 3.162. 10^x = e^(x·ln(10)).

📌 Summary

Powers of 10: 10^n. Positive n = 1 followed by n zeros. Negative n = 1/10^|n|. 10^0 = 1. Scientific notation: a×10^b. SI prefixes (kilo, mega, milli, micro) map exponents to names. Fundamental in metric system, science, and engineering.

✅ Verification Tip

For 10^n with positive n: count zeros. 10³ = 1000 has 3 zeros. For negative n: 10^(-3) = 0.001 has 3 digits after decimal. Check SI prefix: 10³ = kilo.
