Very nice
Fabulous, Sir!!!
10658/ 146= 73
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
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?
Definitely, Will try.
Thanks.
