give an example were you would encounter multiplying exponents
ex. finding the area of a football with small numbers
(length * width)
100
how do you subtract exponents that have the same base
subtract the two exponents of the bases and put it on the original base
2*10^6-2*10^3
2*10^3
100
how do you divide in scientific notation
you subtract the coefficient and then the exponents
200
what is 7*10^3+2*10^-3
7000.002
200
How can you write this as a addition problem 7^5*7^2
7^5+2
200
give an example where you would subtract in scientific notation
you have 5*10^4 pages in a drawing book and you give 4*10^3 to your brother
200
give an example of where you might find dividing in scientific notation
a family has 10*10^4 and a phone cost 10*10^0 and your family buys five phones
300
What is 2*10^9+5*10^1
2000000050
300
what is a^3*a^4
a^7
300
true or false when you take two equal bases and subtract them (they have different exponents)
subtract the exponents keep one of the bases
300
what is the difference between subtracting and dividing exponents
the difference is that for dividing you take both the exponent and the base
400
In the year 2010 the population of Wyoming was approximately 5.63*10^5. the population of Vermount was about 6.25*10^5
what is the population of the two states in the year of 2010
1.188*10^6
or 1188000
400
apple Earns 4*10^ 2 for every iPhone bought and one thousand phones are bought how much money is spent total
400,000
400
what is 10*10^2-10*10^0
10*10^2
400
can you divide numbers with negative exponents in scientific notation
yes you can you would just make the number smaller its basically square rooting the number
500
can you add numbers in scientific notation that are raised to different powers
you cannot
but you can simply the number by rewriting one or more numbers so that all of the numbers are raised to the same power
500
true or false when a number is raised to the power of zero the number is always zero
false a number to the power of zero is that number
EX. 4^0=4
500
is there a rule for subtracting in scientific notation
yes
500
can you divide in scientific notation if the number has a negative exponent
yes you can it would take the number and move the decimal up
4*10^-2
.004
