Exponents and Scientific Notation
Slide an exponent and watch a number expand or collapse into scientific notation.
Hands-on lab
Slide the exponent
3.4 × 104
= 34,000
Scientific notation check
A is between 1 and 10, so this is scientific notation.
Missions
- Write a number in scientific notation
- Make a tiny number (n ≤ −3)
1/2 complete
Guided questions
When is the exponent negative? What kind of number is that?
Reflection
Why must the leading factor in scientific notation satisfy 1 ≤ |A| < 10?
