0.25 + 1 + 4 + 16 + 64 enter the values used in finding a partial sum. r=? a1=? n=?

 The required values are

Step-by-step explanation:  We are given a partial sum as follows :

0.25 + 1 + 4 + 16 + 64.

We are to find the values of

From the given partial series, we note that

the series is a geometric one with first term 0.25 and common ratio calculated as follows :

Also, since there are 5 terms in the given sum, so the value of n is 5.

Thus, the required values are

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
