Answer:

Step-by-step explanation:
The given expression is

First, we need to factor each denominator

So, the least common factor (LCF) is
, because they are the factors that repeats.
Now, we diviide the LCF by each denominator, to then multiply it by each numerator.

Then, we factor the numerator, to do so, we need to find two numbers which product is 10 and which sum is 7.

Therefore, the expression is equivalent to

Answer:
the first one
1, 2, 3, 4, 6, 9, 12, 18, 36
Answer:
<h3>1/24</h3>
Step-by-step explanation:
The race car is doing 8 laps in 1/3 hour, in one hour the car is doing:
8laps * (1/3) hour) = 8*3 laps / 1hour = 24 laps/hour.
Now, to complete one lap, the car will it take:
1 lap * (1 hour / 24 laps) = 1/24 hours the race car requires to complete 1 lap. Right answer is:
<h3>1/24</h3>
Answer:
The first four terms are 3,9,27,81
Step-by-step explanation:
<u>Step :-1</u>
Given first term of sequence is 
Given 'n' t h term is
.............(1)
here we put n = 2 in equation (1)

..............2
put
in equation (2)

put n=3 in equation (1)



put n= 4 in equation (1)



The first four terms of the sequence is
3 , 9, 27 , 81 ....this is geometric sequence
a =3 and ratio term is r =3
