Comparing Scientific Notation

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 compare numbers in scientific notation?

Back

Compare the exponents first; the number with the larger exponent is greater. If the exponents are the same, compare the coefficients.

Front

What is the coefficient in scientific notation?

Back

The number that is multiplied by the power of ten, typically a number between 1 and 10.

Front

Convert 5 x 10^3 to standard form.

Back

5000.

Front

Convert 2.3 x 10^-4 to standard form.

Back

0.00023.

Front

Which is greater: 4.5 x 10^6 or 3.9 x 10^7?

Back

3.9 x 10^7 is greater because 7 > 6.

Front

Order the following from least to greatest: 1.2 x 10^5, 3.4 x 10^4, 2.1 x 10^5.

Back

3.4 x 10^4, 1.2 x 10^5, 2.1 x 10^5.

Front

What does the exponent in scientific notation indicate?

Back

The exponent indicates how many places to move the decimal point.

Front

If two numbers have the same exponent, how do you determine which is larger?

Back

Compare the coefficients; the larger coefficient indicates the larger number.

Front

What is the standard form of 7.8 x 10^2?

Back

780.
