Best ResponseYou've already chosen the best response.0Assuming that a,b,c,d are all positive then we have \(a^3\geq 3\sqrt[3]{b^3c^3d^3}=3bcd\) Hence \[a\geq \sqrt[3]{3bcd}\] So \(\sqrt[3]{3bcd}\) is the minimum value of \(a\).

Best ResponseYou've already chosen the best response.0i thnk it is , if b=c=d then a^3 = b^3 + b^3 + b^3 =3b^3

Best ResponseYou've already chosen the best response.0hey the answer is 9 i think

anonymous

Best ResponseYou've already chosen the best response.0because by hit and trial method 9 is the least number that satisfies the given condition 9^3 = 8^3 + 6^3 + 1^3 729 = 512 + 216 + 1 729 = 729

Best ResponseYou've already chosen the best response.0but where did you get those 8, 6 and 1?

Best ResponseYou've already chosen the best response.0if a^3 = b^3 + c^3 + d^3 hence i thought that a must be greater than b, c and d. so if a = 9 hence b , c and d will be among 1, 2, 3, 4 , 5, 6, 7, 8 i took the cubes of these numbers and took the numbers whose sum contains unit digit as 9.

Best ResponseYou've already chosen the best response.0hence i found many pairs but i found 8, 6 and 1 as correct group . AM I CORRECT PLS TELL ME

Best ResponseYou've already chosen the best response.0i think it is 3,,, try b=1, c=0 d=0, then try c=1,b=0,d=0, then try d=1,b=0,c=0

Best ResponseYou've already chosen the best response.0M VERY SORRY TO ALL OF U THE ANSWER WILL BE 6 6^3 = 5^3 + 4^3 + 3^3 216 = 216

Best ResponseYou've already chosen the best response.0lol...well thats the least i can see ...lol,, so accordingly b cant be equal to c cant be equal to d,....ok....we need to complete the prob specifically...lol

Best ResponseYou've already chosen the best response.0say b=1,c=2 and d=3... also try b0,c=1 and d=3

Best ResponseYou've already chosen the best response.1it is since there are no restrictions on a,b,c,d, right?

Best ResponseYou've already chosen the best response.1i mean of the options for a that is the smallest but there can be smaller

myininaya

Best ResponseYou've already chosen the best response.1like a>infinity would be the smallest lol since a negative to an odd power is still negative and can be negative large
