Exponents and Scientific Notations

The rule of scientific notation is to write all exponents with a base of ____.

• 50

• 5

• 100

• 10

If the exponent is a positive number, ____________.

• you will get a larger number because you are multiplying

• you will get a smaller number because you are dividing

• you will get a larger number because you are dividing

• you will get a smaller number because you are multiplying

If the exponent is a negative number, _____________.

• you will get a larger number, because you are dividing

• you will get a smaller number, because you are dividing

• you will get a larger number because you are multiplying

• you will get a smaller number because you are multiplying

The first term in scientific notation must be _________.

• greater than 0 and less than 10

• greater than or equal to 1 and smaller than 10

• greater than 1 and less than 9

• greater than 0 and less than 9

How would you write -564,000,000 in scientific notation?

• 5.64 x 10^-7

• 5.64 x 10^-8

• -5.64 x 10⁸

• -56.4 x 10⁷

What is the ONLY thing that matters when adding and subtracting numbers in scientific notation?

• That the exponents are different

• That the constants are the same

• That the exponents are the same

• That both constants are positive

Add the scientific notation:

(6.2 x 10²) + (9.7 x 10⁰)

• .6297 x 10²

• 6.297 x 10⁰

• 6.297 x 10³

• 6.297 x 10²

Add with 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

Divide the scientific notation: (6.9 x 10⁷) / (2.3 x 10^-3)

• 3 x 10¹⁰

• 3 x 10⁴

• 3 x 10^-4

• 3 x 10^-11

Divide the scientific notation:

5.2 x 10¹³ / 1.5 x 10⁷

• 3.9 x 10⁶

• 4 x 10²⁰

• 3.4 x 10⁶

• 3.9 x 10²⁰
