for Scientific Notation
It helps us write large and small numbers easier :)
write this number in scientific notation:
47,000
4.7 x 10^4
solve the following equation
3.5 X 10^2 + 4.3 X 10^2
7.8 x 10^2
solve the following equation:
(2 X 10 ^3) x (4 x 10^4)
8 x 10^7
8 x 10^7
-----------
4 x 10^2
2 x 10^5
When you write a Large number from standard form to scientific notation you move the decimal point to which direction...
example: 2,500
you move the decimal point to the left
example: 2.5 x 10^3
write the following number in scientific notation: 320
3.20 x 10^2
solve the following equation:
9.87 x 10^4 -- 3.64 x 10^4
6.23
solve the following equation:
(9 x 10^3) x (2 x 10^5)
18 x 10^8 = 1.8 x 10^9
When you add and subtract numbers in scientific notation the exponents must be...
the exponents must be the same number
write the following number in scientific notation:
4523000
4.523 x 10^6
3.4 x 10^2 + 4.57 x 10^3
4.91 x 10^3 or
49.1 x 10^2 = 4.91 x 10^3
solve the following equation:
(2 x 10^-2) x (8.9 x 10^-2)
44.5 x 10^-4 = 4.45 x 10^-3
6.8 X 10 ^9
----------------
2 x 10^5
When you multiply numbers in scientific notation you........ the exponents
hint: think of the law of exponents
add
write the following number in scientific notation:
0.00000032
3.2 X 10^ -7
here are Toyotas quarterly earnings for 2022:
quarter 1: 2.65 X 10^8
quarter 2: 1.6 x 10^8
quarter 3: 2.25 x 10 ^8
quarter 4: 6.1 x 10^6
what is the total sum of all the quarterly earnings for google in 2022:
6.561 x 10^8
(2.1 x 10^2) x (3.2 x 10^4)
6.72 x 10^6
9.60 x 10^7
______________
1.60 x 10^4
6.00 x 10 ^3
when you divide numbers in scientific notations you......the exponents
hint: think if the law of exponents
subtract the exponents
write the following number in scientific notation:
0.94300 X 10^ -1
9.43 X 10^ -1 or 9.4300 x 10^ -1
the mass of earth id 5.29 x 10^24kg. The mass of Pluto is 13, 000, 000, 000, 000, 000, 000, 000 kg. compared to Pluto how much greater is Earth's mass than Pluto's mass?
hint: greater than means you "take away" to compare the answer :p
5.887 x 10^24 or 588.7 x 10^22
