Explanation
The correct answer choices are all written in scientific notation, which is a way to express very large or very small numbers using powers of 10. In scientific notation, a number is written as a coefficient multiplied by 10 raised to a power. For example, 5.36 x 10^5 means 5.36 multiplied by 10 raised to the power of 5. The other answer choices that are also in scientific notation follow the same pattern, with a coefficient and a power of 10.

Explanation
The given answer includes all the options that are written in standard form. Standard form is a way of writing numbers that includes a decimal point and digits after it, or a number multiplied by a power of 10. In this case, options 2.450, 2,450, 345.345, and 792,098 are written in standard form as they all have a decimal point and digits after it. The option 3.45 X 10^2 is also in standard form as it is a number multiplied by a power of 10. Therefore, the correct answer includes all the options that are written in standard form.

Is this statement true or false? The Earth's mass is about 5,973,600,000,000,000,000,000,000 kg. In scientific notation, this is written as  5.9736   X 1024 kg.

• A.

True

• B.

False

A. True
Explanation
The statement is true because the Earth's mass is indeed approximately 5,973,600,000,000,000,000,000,000 kg, which can be expressed in scientific notation as 5.9736 x 10^24 kg.

Find the answer to the following question in Scientific Notation: 0.0000056 =

• A.

56 X 10 ^-6

• B.

5.6 X 10 ^6

• C.

5.6 X 10 ^-6

• D.

5.6 X 10 ^-5

C. 5.6 X 10 ^-6
Explanation
The given number is 0.0000056, which can be written in scientific notation as 5.6 x 10^-6. This is because the decimal point is moved 6 places to the right, resulting in a coefficient of 5.6, and the exponent is negative since the original number is less than 1.
