  1. Multiplying and Dividing in Scientific Notation
  
  2. Multiplying Numbers in Scientific Notation • Multiply the base numbers together. • Then add the exponents to get the power of 10. • General formula: (N X 10x) (M X 10y) = (N) (M) X 10x+y
  
  3. Example 1 • Given: (3.42 X 105)(4.67 X 109) • Multiply bases: 3.42 X 4.67 = 15.97 • Add Exponents: 105+109=105+9=1014 • Answer: 15.97 X 1014 • Shift Decimal left one place. • Final Answer: 1.597 X 1014
  
  4. Example 2 • Given: (2.93 X 10-2)(8.3 X 10-5) • Multiply Bases: 2.93 X 8.3 = 24.319 • Add Exponents: 10-2+10-5=10-2+(-5)=10-7 • Answer: 24.319 X 10-7 • Shift decimal left one place. • Final Answer: 2.43 X 10-6
  
  5. Practice Worksheet Practice Multiplying in Scientific Notation (2.4 X 10-3)(4.5 X 10-3) = (5.67 X 10^3)(3.9 X 10^-6) = (4.78 X 107)(9.3 X 10-2) = (8.9 X 10^-2)(6.5 X 10^4) = (3.4 X 108)(5 X 103) =

  9. Dividing Numbers in Scientific Notation • Divide the base numbers. • Then subtract the exponents to get the power of 10. • General formula: N X 10x / M X 10y = N/M X 10x-y
  
  10. Example 1 • Given:8 X 10-3 / 2 X 10-2 • Divide bases: 8/2=4 • Subtract exponents: (-3)-(-2)=-1 • Answer: 4 X 10-1
  
  11. Example 2 • Given:3.45 X 102 / 1.23 X 10-5 • Divide bases: 3.45/1.23= 2.81 • Subtract exponents: (2)-(-5)=7 • Answer: 2.81 X 107
