Applying Operations on Numbers Expressed Using Scientific Notation to Solve Mathematical and Real-World Problems

Solve : (2 × 10¹²) × (1.5 × 10⁴)

• (9 × 108^.6)

• (3 × 1.0¹⁶)

• (3 × 10¹⁶)

• (3.5 × 10¹⁶)

How many times larger is 5 x 10⁷ than 5 x 10²?

• 1 x 10⁶

• 1 x 10⁴

• 1 x 10⁵

• 1 x 10⁹

Add using scientific notation

(5.2 x 10⁷) + (3.01 x 10⁴)

• 5.20301 x 10¹¹

• .520301 x 10⁷

• 5.20301 x 10⁷

• 5.20301 x 10⁸

(20 x 10⁵⁰) / (4 x 10¹⁵)

• 2.4 x 10⁵¹

• 5 x 10⁶⁵

• 8 x 10⁶⁶

• 5 x 10³⁵

Match the process to the correct way to solve

• Make the exponents MATCH, +/- decimals

• Adding and Subtracting with Scientific Notation

• Multiply the decimals, ADD the exponents

• Dividing with Scientific Notation

• Divide the decimals, SUBTRACT exponents

• Multiplying with Scientific Notation
