First law of exponents
Solve:
32 x 36
32+6= 38
Write in exponential Notation
5 x 5 x 5 x 5 x 5
55
Evaluate the expression
40
=1
Is this number in scientific notation? If not, explain.
1.2654 x 105
Yes
(3.3 x 105) + (4.2 x 105)
(3.3 + 4.2) x 105= 7.5 x 105
Solve
107/104
107-4=103
Write in exponential notation
(-2) x (-2) x (-2) x (-2) x (-2) x (-2) x (-2)
(-2)7
(56)2
56 x 2= 512
same as saying 56 x 56= 56+6 = 512
Is this number in Scientific notation? If not, explain.
.098745 x 104
No because the decimal is not between 1 and 10.
(5.8 x 107) - (3.3 x 107)
(5.8-3.3) x 107= 2.5 x 107
Simplify. Keep answer in exponential notation.
c2 x 5 x c4 x 53 x c
c2+4+1 x 51+3 = c7 x 54
Write in expanded form

Mrs. Anderson makes $200,000 each year. If Mrs. Anderson continues to make the same amount each year, how much money would she have after 12 years (1.2 x 101)?
(2 x 105) x (1.2 x 101) = (2 x 1.2) x (105 x 101)=
2.4 x 105+1=2.4 x 106
In a storage warehouse, each container weighs 63 pounds. If there are 65 containers, how much do the containers weigh in all? Leave answer in exponential form.
63 x 65= 68 pounds

The population in Copperopolis is approximately 88,000. Only 44,000 people golf. There are
2.2 x 102 golf balls from each person that plays golf at the bottom of the lake from missing the hole. How many total golf balls are at the bottom of the lake? Write answer in scientific notation.
(4.4 x 104) x (2.2 x 102) = (4.4 x 2.2) x (104 x 102)
= 9.68 x 104+2 = 9.68 x 106
Mrs. Harding regularly volunteers at a local shelter. She unexpectedly was given a very large amount of diamonds.She would like to share these diamonds with the members of the shelter. She has 311 diamonds that she will be sharing with members she helps at the shelter. There are 33 members that she services at the shelter. How many diamonds will each member get? Leave answer in exponential form
311/33= 311-3=38
Each member will get 38 diamonds
