Answer:
Step-by-step explanation:
We want to find the sum of all even numbers from 0 to 175.
The series will be:
The explicit formula for this is 
, where 
.
We need to find how many terms are there.
The sum of terms is given by:
Substitute n=88, 
and l=174 to get:
? I'm not sure what you are asking?
Answer:
Below
Step-by-step explanation:
Notice that 81 = 9 * 9
So here is the first expression:
● 9^2
9 is 3^2 so 9^2 is 3^4
That's another expression
● 3^4
81 = 9*9 = 3*3*3*3 = 3^3 *3
That's another expression
● 3*3^3
You can keep manipulating the product and create many expressions like:
● 3^2 * 3^2
● 9 * 3^2
