Scientific Notation Numbers expressed in scientific MUST be expressed as a product of: a number greater or equal to one, but less than ten And A power of ten

5
Are these Numbers in Scientific Notation? 33.1 x x x x x x x 10 5

6
What is in Scientific Notation? 1. Place a decimal point after the first non-zero digit(giving you a number greater or equal to 1 but less than 10) Drop the trailing zeros 5.61 Count the number of places(boinks) the decimal was moved Express this number as an exponent of x 10 11

9
What is the Value of Each Exponent? = 3.1 x 10 ? = 8.1 x 10 ? 5.3 x 10 8 = ? 9.9 x = ? 5.3 x 10 2 = ? 9 x 10 7 = ? x 10 5 = ?
