If 35 + 125 = 17.88, then what will be the value of 80 + 65 ?
Answer: Option
Explanation:
35 + 125 = 17.88
35 + 25 x 5 = 17.88
35 + 55 = 17.88
85 = 17.88
5 = 2.235
80 + 65 = 16 x 5 + 65
= 45 + 65
= 105 = (10 x 2.235) = 22.35

Sr 80 + 6 Sr 5.
It means that Sr 16 * 5 + 6 Sr 5.
=> 4 Sr 5 + 6 Sr 5.
Then simplify 10 Sr 5 = 10* sr 5.
Sr 5 is = 2.235 * 2.235.
10 * 2.232 = 22.35.

Easy way to find R5 value.
2 square is 4.
3 square is 9.
So, find the number between 2 and 3.we choose 2 because 2 square is 4 less than 5.
5/2=2.5.
Average between 2 and 2.5.
2 + 2.5/2 = 4.5/2 = 2.235.
So, the R5 value is 2.235.

Easiest way is;
8√5=1788/100.
=> (10/8)*8√5 = (1788/100) * (10/8) = 223.5/10 = 22.35.
8√5=1788/100.
=> (10/8)*8√5 = (1788/100) * (10/8) = 223.5/10 = 22.35.

Here you divide 17.88 by 8 then why you multiplied 2.235 by 10?

We have to divide 17.88 by 8, so root 5 = 2.235.
