Scientific Notation Flashcard

Front

What is scientific notation?

Back

A way of expressing numbers that are too large or too small to be conveniently written in decimal form, using powers of ten.

Front

How do you convert a large number to scientific notation?

Back

Move the decimal point to the left until only one non-zero digit remains to the left of the decimal. Count the number of places moved; this becomes the exponent of 10.

Convert 520,000,000 to scientific notation.

Back

5.2 x 10^8

Front

How do you convert a small number to scientific notation?

Back

Move the decimal point to the right until only one non-zero digit remains to the left of the decimal. The exponent of 10 will be negative, indicating how many places the decimal was moved.

Convert 0.000457 to scientific notation.

Back

4.57 x 10^-4

Front

What is the result of (8 x 10^4) - (2 x 10^4)?

Back

6 x 10^4

Front

What is the result of (6 x 10^6) / (2 x 10^3)?

Back

3 x 10^3

Front

What is the sum of (7.7 x 10^2) + (1.1 x 10^2)?

Back

8.8 x 10^2

Front

What does the exponent in scientific notation represent?

Back

The exponent indicates how many places the decimal point has been moved and whether the number is large (positive exponent) or small (negative exponent).

Front

What is the general form of scientific notation?

Back

A x 10^n, where 1 ≤ A < 10 and n is an integer.
