NEGATIVE POWERS OF TEN SOL 7 1 a

NEGATIVE POWERS OF TEN SOL 7. 1 a To view this video, please have the following: 1. Notebook paper or practice sheet 2. As you review, please take notes and complete the activities.

EXPONENT An exponent is the number that indicates how many times the base is used as a factor

exponent base Ten to the 3 rd power = 10 x 10 = 1000

POSITIVE POWERS OF TEN =1 =10 x 10 = 1000 =10 x 10 x 10 = 10, 000 =10 x 10 x 10=100, 000

Negative Exponents for powers of ten are used to represent numbers between 0 and 1. Negative exponents will have equivalent forms of FRACTIONS and DECIMALS. These exponents can be investigated through patterns! http: //virtualnerd. com/pre-algebra/factors-fractions-exponents/scientificnotation/scientific-notation-powers-ten/exponents-negative-ten Click on the video to examine the patterns.

• Answer Now

• Common mistakes – many think because the exponent is negative, the equivalent solutions are negative. That is wrong. Because the exponent is negative, the equivalent forms are a fraction and a decimal! Answer Now

WHICH IS NOT AN EQUIVALENT FORM FOR 0. 001? • The first three all equal 0. 001. They are equivalent forms. The only one that is not is item # 4. Item # 4 has a positive exponent so it’s solutions are not a fraction nor a decimal. It is equivalent to 10 X 10 and 1, 000. Answer Now
