`x- sqrt121=0, y^(2) - 121= 0`

In the following questions two equation numbered I and II are given You have to solve both equations and . . . . . (i) x-sqrt(121)=0 (ii) y^(2)-121=0

Factorise: y^(2)-121

(1)/(4)xx sqrt ([(12.1)^(2)-(8.1)^(2)] div [(0.25)^(2)+(0.25)(19.95)]) .

The value of sqrt(0.121) is (a) 0.011(b)0.11(c)0.347(d)1.1

The simplified value of sqrt((1.21 xx 0.9 )/(1.1 xx 0.11 )) is -

What is the vaue of sqrt 121 + sqrt 12321 + sqrt 1234321 + sqrt 123454321

sqrt([(12.1)^(2)-(8.1)^(2)]-:[(0.25)^(2)+(0.25)(19.95)])
