Find the value of "n" where 348 + 31996 +33943+33n.
Read Solution (Total 6)
-
- (3^16 ) ^3+3^1996+3^3943+(3^n)^3
So it is equivalent to a^3+3a^2b+3ab^2+b^3
So,3*(3^16)^2*3^n=3^1996
3^(33+n)=3^1996
n=1963

- Right question is 3^48+3^1996+3^3943+3^3n
so check the difference b/w to power 1996-48=1948.
again check then we will get 3943-1996=1947.
so here we can see that the difference b/w 1st two power and 2nd two power decreased by 1.
so we can write for 3rd power i.e.
3n-3943=1946
n=1963 answer - 5 years agoHelpfull: Yes(1) No(0)
