7.NS.1cd Ordering 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 convert a number to scientific notation?

Back

Move the decimal point in the number until only one non-zero digit remains to the left of the decimal, then multiply by 10 raised to the number of places the decimal was moved.

Front

What is the general form of scientific notation?

Back

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

Front

How do you compare two numbers in scientific notation?

Back

First compare the exponents. If they are the same, then compare the coefficients.

Front

What does it mean to order numbers in descending order?

Back

To arrange numbers from largest to smallest.

Front

What is the value of 5 x 10^3 in standard form?

Back

5000.

Front

What is the value of 3.2 x 10^8 in standard form?

Back

320,000,000.

Front

What is the value of 1.2 x 10^8 in standard form?

Back

120,000,000.

Front

What is the value of 7 x 10^5 in standard form?

Back

700,000.

Front

How do you determine which number is larger: 5.79 x 10^-7 or 5.32 x 10^-7?

Back

Since the exponents are the same, compare the coefficients: 5.79 > 5.32, so 5.79 x 10^-7 is larger.
