Then multiply the two of them together. What is your answer?

Homework Punchline worksheets 11.6 & 11.7 “What Did Professor Utterbunk Say When Asked: Have You Ever Heard of the Planet Saturn?” I’M NOT SURE BUT IT HAS A FAMILIAR RING “What Did People Say After Two Satellite Dishes Got Married?” THE WEDDING WAS DULL BUT THE RECEPTION WAS GREAT

Objective SWBAT use scientific notation to represent numbers.

Section 8.4, “Use Scientific Notation” Scientific notation is a form to write very large or very small numbers. Did you know that the population of the world is about 5,600,000,000? Instead of writing this number with so many zeros, you can use the following form:

Section 8.4, “Scientific Notation” A number is written in scientific notation if it has the form: where c is greater than or equal to 1 but less than 10. Standard form Product form Scientific notation **HINT: How many spots has the decimal point moved?

Write the number in scientific notation. 1) 2) Write the number in decimal form. 3) 4)

Multiplying with Scientific Notation To multiply two numbers that are written in scientific notation, you can use the rule for multiplying powers with like bases. Find the product of and Write the product Reorder Multiply Write in scientific notation

Evaluate the quotient. Decimal form Write the product Write in scientific notation Decimal form

Evaluate the product. Decimal form Find the product of and Write the product Reorder Multiply Write in scientific notation Decimal form
