:
-
To simplify a square root, we extract factors which are squares, factors that are raised to an even exponent.
-
Factors which will be extracted are:
-
Factors which will remain inside the root are:
-
To complete the simplification we take the square root of the factors which are to be extracted. We do this by dividing their exponents by
:

-
To simplify a square root, we extract factors which are squares, factors that are raised to an even exponent.
-
In our case however, all the factors are only raised to the first power and this means that the square root can not be simplified

Answer:
a=28
Step-by-step explanation:
use inverse operations
Answer:
This is the concept of geometric series. We are required to find the recursive formula for year n. Here we will use the formula;
nth=ar^(n-1)
where;
a=first term
r=common ratio
n=nth term
Thus
a=8.50
r=(8.85)/(8.50)=1.0412
thus the formula will be:
nth=8.50(1.0412)^n
