Answer:
4.446 then 4.464 then 5.228
Step-by-step explanation:
Hope this HELPS :D
Unfortunately your teacher is using x as both a variable and a multiplication sign. This is something that can be avoided by using something like the asterisk symbol to indicate multiplication.
Anyways, notice how the expression 
shows up twice. Once in the numerator (the entire numerator) and once again in the denominator (nearly the whole thing)
Let's replace that messy expression with the variable y. So we're letting 
This means,
At this point you can probably see how to get 
from here. The y terms cancel out when we divide leaving 1 up top and 3^x down below.
The answer is 207.
Search up the site Mathaway. It gives you answers.
The first box would be 3.14 then second box would be the pi symbol and the third box would be 22/7
The required number which when decreased by 8 is divisible by 21, 27, 33, and 55 is 10403.
We need to find the smallest number which when decreased by 8 is divisible by 21, 27, 33, and 55.
<h3>What is LCM?</h3>
The least common multiple is also known as LCM (or) the lowest common multiple in math. The least common multiple of two or more numbers is the smallest number among all common multiples of the given numbers.
We find the LCM of 21, 27, 33, and 55.
3 | 21 27 33 55
3 | 7 9 11 55
3 | 7 3 11 55
7 | 7 1 11 55
5 | 1 1 11 55
11 | 1 1 11 11
| 1 1 1 1
When decreased by 8, we have to add 8 in the LCM of the numbers.
That is 10395+8=10403
Therefore, the required number when decreased by 8 is divisible by 21, 27, 33, and 55 is 10403.
