Very nice
Fabulous, Sir!!!
a=1^2, b=4^3, c=3^4. Note that the denominators of the two terms are the same, 146. So, the given number N = [a^2+b^2+c^2]/(a+b+c) = a+b+c -2 [ab+bc+ca]/(a+b+c) = 146 - (2/146)[145+5184] = 146- 1/73[146 + 5183] = 144- 5183/73 = 144-71 = 73.
Let a=1^2, b=4^3 and c=3^4. (a+b+c)^2=a^2+b^2+c^2-2(ab+bc+ac), thus a^2+b^2+c^2=(a+b+c)^2-2(ab+bc+ac). Or, 2^12+81^2+1=a^2+b^2+c^2. We have to focus that 1^2+4^3+3^4=5^2+11^2 (same denominator). After simplifications, we'll get E=73
10658/ 146= 73
you could divided E n to E
Ridiculously awkward
Can you make this problem more than manipulation of symbols by explaining in what circumstances one would encounter such an expression In scientific research?

An absurd nitpicking! Why should an algebraic manipulation be connected to scientific researches?

@@woobjun2582 Pure math is important by itself, but when it turns out that math problems have real applications we also learn unexpected things about the universe and its mathematical nature.
