Back

A way of expressing numbers as a product of a number between 1 and 10 and a power of 10.

Front

What is the format of a number in scientific notation?

Back

The format is a x 10^n, where 1 ≤ a < 10 and n is an integer.

Front

Convert 0.00045 to scientific notation.

Back

4.5 x 10^-4

Front

What is the first step in adding numbers in scientific notation?

Back

Ensure both numbers have the same exponent.

Front

How do you add (3.2 x 10^5) and (4.5 x 10^5)?

Back

(3.2 + 4.5) x 10^5 = 7.7 x 10^5

Front

What is the result of (1.2 x 10^3) + (3.4 x 10^2)?

Back

1.2 x 10^3 + 0.34 x 10^3 = 1.54 x 10^3

Front

Convert 7,500,000 to scientific notation.

Back

7.5 x 10^6

Front

What is the rule for multiplying numbers in scientific notation?

Back

Multiply the coefficients and add the exponents.

Front

What is the result of (2 x 10^3) * (3 x 10^2)?

Back

6 x 10^5

Front

How do you divide (8 x 10^6) by (4 x 10^2)?

Back

(8/4) x 10^(6-2) = 2 x 10^4
