2.) If you were to change a number in Scientific Notation, which
number would indicate the number of places you will move the
decimal? The Multiplier OR The Exponent
3.) Fill in the Blank: If a number has a ____________ exponent,
move it to the right to change it into standard form. If the
number has a negative exponent, move it to the __________ to
change it into standard form.
Solve: Change each number into Scientific Notation

8.) Fill in the Blank: When adding or subtracting numbers in scientific
notation, first choose the number with the _______________
exponent. Next, convert each number to have the same
exponent by moving the decimal to the ____________.36 8.512N04739.50 125They use it because they have to reduce it because they will get a answerlike this:2.4e80 they use it so u don’t have a e in thereDecimalRightLeft Scientific Notation Study GuideName: __________________ Period:__________

9.) (6 x 106) – (5 x 105)
10.) (2 x 105) + (8 x 104) + (8.28 x 105)
11.) (3.62 x 10−2) + (7.8 x 10−5)
12.) Fill in the Blank: When Multiplying numbers in scientific
notation, first use the _______________ Rule of Exponents. Next,
add your exponents and _____________ your multipliers. If needed,
change your number into scientific notation.
13.) When Dividing numbers in scientific notation, first use the
Quotient Rule of Exponents. Next, _________ your exponents and
______________ your multipliers. If needed, change your answer
into scientific notation.
14.) Circle the correct choice: When changing numbers into scientific
notation, move the decimal to the right and then (add/subtract) the
number of places you moved the decimal, to the exponent.Efg1 I110800000.0302280OExponentAddAddSubtract Scientific Notation Study GuideName: __________________ Period:__________
15.) When changing numbers into scientific notation, if moving the
decimal to the (left/right), subtract the number of places you moved
the decimal, to the exponent.
Solve: Show your work and be sure to write your final answer in
Scientific Notation.
16.) (7.1 x 10−5)(6.7 x 10−6)
17.) (1.6 x 106)
(4 𝑥 106)
18.) Be prepared to solve at least one word problem:
When the Sun makes an orbit around the center of the Milky Way, it
travels 2.025 x 1014 kilometers. The orbit takes 225 million years.
At what rate does the Sun travel? Write your answer in scientific
notation. (Hint: use formula Rate = distance / time)O76275 10
