Answer 5

im not allowed >.>

Answer 6

how u got this ?

Answer 7

rough mathematics :P
1*1=1
1.2*1.2=1.44
1.3*1.3=1.69
1.4*1.4=1.96
but we need 1.8 so it must lie between 1.3*1.4 so take it as 1.35 (u can check via calculator too thats correct)
thats just my way of doing pellet calculations because every second in IIT exam will be worth so i just have to make approx calculations

Answer 8

i cant solve for 10^-6

Answer 9

sqrt (10^(-6)) = 10^(-6)^(1/2) = 10^-3
1/10^-3 = 10^3
