hi there,
__________________________________________________
__________________________________________________

answer of question number 9 is 11,
as,
the numbers are as follows
10,20,30,40,50,60,70,80,90,100
___________________________________________________

for the 8th one,
LHS,
x+1/x = 5
sq ob/s
(x+1/x)²=25
x²+1/x²+2 = 25 {2(x)(1/x) = 2}
so,
x²+1/x² = 23
from this we can say that
 \frac{x^4+1}{x^2} =23
