Some text here about the topic of discussion

​How to Multiply: Use the associative property to group

​Solve (2.2 X 10³) X (2.0 X 10⁵)

Multiple Choice

Solve (1.0 X 10⁵) X (2.0 X 10⁶)

• 2.0 X 10¹¹

• 3.0 X 10³⁰

• 1.0 X 10¹¹

• 3.0 X 10¹¹

Multiple Choice

​How to divide in scientific notation: Similar to multiplying, use associative to group and then divide.

​Solve: 1.5 X 10⁸ ÷ 3.0 X 10²

Multiple Choice

Solve (2.0 X 10¹¹)÷ (4.0 X 10⁵)

• 0.5 X 10⁶

Multiple Choice

Solve (6.0 X 10²⁰) ÷ (3.0 X 10⁹)

• 2.0 X 10¹¹

• 1.8 X 10³⁰

• 2.0 X 10³⁰

• 1.8 X 10¹¹

​How to add and subtract: Write the numbers in expanded form.

​Solve 6.2 X 10⁹ - 4.5 X 10⁷

Multiple Choice

Solve 7.5 X 10⁹ - 3.0 X 10⁵

• 4.5 X 10⁴

• 7.4997 X 10⁹

• 7,499,700,000

• 10.5 X 10¹⁴

Multiple Choice

Solve 6.6 X 10⁸ + 4.4 X 10⁷

• 1.1 X 10¹⁶

• 7.04 X 10⁸

• 11 X 10⁸

• 1.1 X 10⁸

​Conclusion: Write two complete sentences about what you learned.
