Algebra Scientific Notation
Warm-up • Complete the table. 10,000 1,000 100 10 1 What pattern do you see between the exponents and the standard form number?
In your notes • Complete the table. .0001 .001 .01 .1 What pattern do you see with the exponents and the standard form number?
With a calculator • Evaluate 890 45,100 .00722 .8132 What pattern do you see with the exponents and the standard form number?
Without a calculator • Evaluate 610 7,050 .000125 .082
Scientific notation • Scientific notation is a way of writing numbers using powers of ten. • Scientific notation uses a number between 1 and 9.9999… with a power of ten. 4,081,000 = • 4.081 • x 106 Exponent is equal to the number of places we moved the decimal Move decimal behind first digit (6 places)
Practice • Write the number in scientific notation.
Without a calculator • Write in regular (standard) form 2,390 456,000 .0198 .003092
Summary • Scientific Notation is not a calculation, it is just another way of writing a number. • Scientific Notation is useful when dealing with very large or very small numbers. • When converting numbers into and out of scientific notation, we move the decimal according to the exponent on the 10.
