3.8 Exponents — The Math Shorthand That Changed Everything | Contemporary Mathematics
After this lesson you will be able to…
- Learn why exponents are essential for representing extremely large numbers efficiently.
- Understand the terms 'base' and 'exponent' and their roles in mathematical shorthand.
- Learn to multiply identical bases by adding their exponents together.
- Understand that the product rule only applies when the bases are exactly the same.
- Learn to divide identical bases by subtracting the bottom exponent from the top.
- Discover why any non-zero number raised to the power of zero equals one.
- Apply an outer exponent to each factor within parentheses when multiplying.
- Apply an outer exponent to both the numerator and denominator of a fraction.
- Learn to simplify an exponent raised to another exponent by multiplying them.
- Understand that a negative exponent indicates a reciprocal, not a negative number.
- Use negative exponents to move terms from the denominator to the numerator, flattening fractions.
- Recap all the exponent rules and their logical interconnectedness.
