己知a,b,c∈R+,且a+b+c=1,证明:√ab+√bc+√ca≤1,证明:bc/a+c己知a,b,c∈R+,且a+b+c=1,证明:√ab+√bc+√ca≤1,证明:bc/a+ca/b+ab/c≥1

己知a,b,c∈R+,且a+b+c=1,证明:√ab+√bc+√ca≤1,证明:bc/a+c己知a,b,c∈R+,且a+b+c=1,证明:√ab+√bc+√ca≤1,证明:bc/a+ca/b+ab/c≥1
己知a,b,c∈R+,且a+b+c=1,证明:√ab+√bc+√ca≤1,证明:bc/a+c
己知a,b,c∈R+,且a+b+c=1,证明:√ab+√bc+√ca≤1,证明:bc/a+ca/b+ab/c≥1

己知a,b,c∈R+,且a+b+c=1,证明:√ab+√bc+√ca≤1,证明:bc/a+c己知a,b,c∈R+,且a+b+c=1,证明:√ab+√bc+√ca≤1,证明:bc/a+ca/b+ab/c≥1

证明:
因为(bc)^2+(ac)^2]+[(bc)^2+(ab)^2]+[(ac)^2+(ab)^2]>=2abc(a+b+c)=2ab
所以bc/a+ca/b+ab/c>=1
