Let's now multiply two numbers in scientific notation using theGoogle Calculator.

On the Google Calculator, scientific notation is indicated by "EXP", as highlighted here:

Choose one 5 points

To enter scientific notation, we type in the number out in front of the multiplication symbol, then "EXP", then the number in the exponent. For example,would be entered as5, thenEXP, then8:

0:00/0:06

1X

Google Calculator enters the "5" button, then the "EXP" button, then the "8" button. "5E8" appears in the calculator number window.

Note in the output that5E8means.

To multiply two numbers in scientific notation:

0:00/0:15

1X

Google Calculator enters "8", then "EXP", then "5", then "times", then "4", then "EXP", then "-6", then "=" and the number 3.2 appears in the calculator number window.

Now, multiply the numberbyusing the Google Calculator. What is the correct answer in scientific notation?

Note:If you are using a different calculator, the scientific notation button may be different. Sometimes it is represented by anEorEE. Ask your instructor if you are unsure!

(8 x 10)(4 x 107) = 3.2 0:00/0:15
