IF a,b,c are positive then the least value of `(a +b+c)(1//a+1//b +1//c)` is

If a,b,c are positive real number, then the least value of (a+b+c)(1/a+1/b+1/c) is

If, a,b,c are positive and a + b + c =1 , then the least value of 1/a + 1/b +1/c is

If a, b, c are positive real numbers, then the least value of (a+b+c)((1)/(a)+(1)/(b)+(1)/( c )) , is

If a, b, c are positive real numbers, then the least value of (a+b+c)((1)/(a)+(1)/(b)+(1)/( c )) , is
