Is the number written in scientific notation? Why or why not? 3.6x100^7
Is the number written in scientific notation? Why or why not?3.1x10^-5
Pls help me💖
no
yes
review what scientific notation is.
Hi, thanks, @oobleck that looks like you're not the real teacher.
Also could someone help with:
What is the order of theese numbers from LEAST to GREATEST?
2.7x10^8,2.3x10^11,6.5x10^12,4.8x10^21
No one? Ok.
2.7x10^8
2.3x10^11 = 2300x10^8
6.5x10^12 = 65000x10^8
4.8x10^21 = 48000000000000x10^8
still not sure?
To determine whether a number is written in scientific notation, we need to analyze its format and criteria. In scientific notation, a number is typically written in the form of "a multiplied by 10 to the power of b," where "a" is a number between 1 and 10 (inclusive), and "b" is an integer.
Let's discuss the given numbers:
1. 3.6x100^7
To determine if this number is in scientific notation, we need to check if it follows the format of "a multiplied by 10 to the power of b." Here, we have "3.6" as "a" and "100^7" as "b."
To rewrite this number in scientific notation:
--> "3.6" can be expressed as "3.6x10^1" since it is between 1 and 10.
--> "100^7" can be simplified as "10^(2x7)" since "100" is equal to "10^2" and we raised it to the power of 7.
Therefore, the number "3.6x100^7" can be written in scientific notation as "3.6x10^(1+14)" or "3.6x10^15."
2. 3.1x10^-5
In this case, "3.1" is "a" and "10^-5" is "b."
Therefore, the number "3.1x10^-5" is already written in scientific notation.
In summary:
- The number "3.6x100^7" can be rewritten in scientific notation as "3.6x10^15."
- The number "3.1x10^-5" is already in scientific notation.
Please note that the format and criteria mentioned above are widely accepted conventions for scientific notation, but there may be variations or different notations used in specialized contexts.
