1/(1+√2)+1/(√2+√3)+...+1/(√9999+√10000)=99√为根号怎么证明=99
1/(1+√2)+1/(√2+√3)+...+1/(√9999+√10000)=99
√为根号
怎么证明=99
1/(1+√2)+1/(√2+√3)+...+1/(√9999+√10000)=99√为根号怎么证明=99
1/(√n+√(n+1)=(√(n+1)-√n)/(√(n+1)-√n)(√(n+1)+√n)
=√(n+1)-√n
所以原式=√2-1+√3-√2+.+√10000-√9999
=√10000-1=99

变成√2-1+√3-√2+...+√10000-√9999=√10000-1=99
