In radioactive reaction ._(Z)^(A)Xrarr ._(Z+1)^(A)X_(1)rarr ._(Z+2)^(A)X_(2)rarr ._(Z)^(A-4)X_(3) rarr ._(Z+1)^(A-4)X_(4) Successive emission of particles is

The equation: 4._(1)^(1) H^(+) rarr ._(2)^(4) He^(2+) + 2e + 26MeV represnets.

MnO_(4)^(-) is good oxidising agent in different medium changing to - rarr MnO_(4)^(2-) rarr MnO_(4)^(2-) rarr MnO_(2) rarr Mn_(2)O_(3) Changes in oxidation number respectively are -

Evaluate: lim_ (n rarr oo) (1 ^ (4) + 2 ^ (4) + 3 ^ (4) + ... + n ^ (4)) / (n ^ (5)) - lim_ (n rarr oo) (1 ^ (3) + 2 ^ (3) + ... + n ^ (3)) / (n ^ (5))

Evaluate: lim_ (n rarr oo) (1 ^ (4) + 2 ^ (4) + 3 ^ (4) + ... + n ^ (4)) / (n ^ (5)) - lim_ (n rarr oo) (1 ^ (3) + 2 ^ (3) + ... + n ^ (3)) / (n ^ (5))

lim_ (x rarr (1) / (2)) ((8x-3) / (2x-1) - (4x ^ (2) +1) / (4x ^ (2) -1))

Let f: R rarr R be a function such that f(2)=4 and f'(2)=1 . Then, the value of lim_(x rarr 2) (x^(2)f(2)-4f(x))/(x-2) is equal to
