Exponent Rules and Scientific Notation Review

Which is greater? 1.111 x 10¹⁵ or 9.999 x 10³ ?

• They are equivalent.

• There is no way to determine which is greater. The numbers are too big to understand.

• 1.111 x 10¹⁵ is greater because of the larger exponent

• 9.999 x 10³ is greater because 9.999 is larger than 1.111

Which shows the following expression simplified using the properties of powers.

• 3.3 x 10³

• 33 x 10³

• 3.3 x 10^-3

• 3300 x 10³

Simplify. Leave as an exponent.

• 1/27

• (1/3)⁴

• (1/3)⁵

• (1/27)²

Divide:
(6.9 x 10⁷) / (2.3 x 10^-3)

• 3 x 10¹⁰

• 3 x 10⁴

• 3 x 10^-4

• 3 x 10^-11

Write the answer in scientific notation.
4.1 x 10⁵ +   5.5 x 10⁶  =

• 5.91 x 10⁶

• 9.6 x 10⁵

• 9.6 x 10¹¹

• 4.65 x 10⁵

Which is the largest?

3.1 x 10^-4
9.2 x 10^-5 
9.5 x 10³²
5.9 x 10^-5
2.9 x 10²¹
8.4 x 10¹⁹

• 9.5 x 10³²

• 3.1 x 10^-4

• 8.4 x 10¹⁹

• 4.8 x 10^-6 

Scientific Notation is made up of two number parts. The second part must be an exponent with of base 10.

• True

• False

Evaluate: 12⁰ = ?

• 0
