NaOH is a strong base that dissociates completely Therefore [OH-] = [NaOH] = 0.001M First calculate the pOH of the solution : pOH = -log [OH-] pOH = -log 0.001 pOH = 3.00 pH = 14.00 - pOH pH = 14.00 - 3.00 pH = 11.00

10 raise to 2n-1 +1 is divisible by 11

Posted by Aditi Singh 6 years, 10 months ago

CBSE > Class 11 > Mathematics

N Kansara 6 years, 10 months ago

10^(2n-1) +1 is divisible by 11. We will prove this statement by induction. For n = 1 this is true, Now we assume that it is true for n = k Therefore 10^(2k-1) + 1 = 11×t (where t is some integer. => 10^(2k-1) = 11×t - 1 ..... equation 1 For n = k + 1 LHS = 10^(2(k+1) - 1) +1 = 100×10^(2k-1) +1 From equation 1 we substitute value of 10^(2k-1), LHS = 100×(11×t - 1) +1 = 11 (100×t + 9) which is clearly a multiple of 11. Hence proved
