It takes 1.7 x 10 ^4 for light from the sun to reach the comet.
<h3>How do scientific notations work?</h3>
The number is written in the form 
where we have 
Scientific notations have some of the profits as:
Better readability due to compact representation
Its value in terms of the power of 10 is known, which helps in the easy comparison of quantities differing by a large value.
A comet is about 
km from the sun.
Light travels at about 
km per second.
= 
Hence, It takes 1.7 x 10 ^4 for light from the sun to reach the comet.

Answer:
The number are 
and .
Step-by-step explanation:
Given as :
The difference between the squares of two number = 3
And , Twice the square of the first number increased by the square of the second number is 9
Now, Let The first number = F
And The second number = S
So , According to question
F² - S² = 3 .......A
2 F² - S² = 9 ........B
Now, solving the equations
( 2 F² - S² ) - ( F² - S² ) = 9 - 3
Or, ( 2 F² - F² ) + ( S² - S² ) = 6
Or, F² + 0 = 6
∴ F =
Putting the value of F in eq A
So, ( )² - S² = 3
Or, 6 - 3 = S²
Or, S² = 3
∴ S = 
So, The number are ,
Hence The number are and . Answer
Answer:
there isn't really an answer
Step-by-step explanation:
use the greatest common denominator (12) for all of them
for 3/12 you dont have to change it,
for 1/6 multiply it by 2, (2/12)
for 1/3 multiply it by 4, (4/12
The least is 2/12 or 1/6
then comes 3/12
then the greatest is 4/12 or 1/3
