Ta có :\(\frac{16\times17-5}{16\times16+11}\)

\(=\frac{16\times\left(16+1\right)-5}{16\times16+11}\)

\(=\frac{16\times16+16-5}{16\times16+11}\)

\(=\frac{16\times16+11}{16\times16+11}\)

\(=1\)

16x 17-5/16 x 16 +11

= 16 x 17 - 16 x 5/16 + 11

= 272 - 5 + 11

= 267 + 11

= 278

bài ko ghi là tính nhanh nên mk ko tính nhanh nha

1872/1716 đi mà làm cho ối ginảô

12/13 x 15/16 x 13/15 : 11/16 = 12/13 x 15/16 x 13/15 x 16/11

= 12/11

Thanks bn iu nhìu!

nhiều thế bn

chia ra dc ko ạ

ktra?

Đk: x>0, x≠1

P=(√x/(√x -1) +√x/(√x +1)):√(4x)/(x-1)

P=((x+√x)/(x-1)+(x-√x)/(x-1)).(x-1)/√(4x)

P=(x+√x + x-√x)/(x-1).(x-1)/√(4x)

P=(2x)/(x-1).(x-1)/√(4x)

P=(2x)/√(4x)

P=√x

Vậy P=√x

\(=\frac{3}{2}\left(\frac{1}{2}-\frac{1}{3}+\frac{1}{3}-\frac{1}{5}+......+\frac{1}{99}-\frac{1}{100}\right).\)

\(=\frac{3}{2}.\left(\frac{1}{1}-\frac{1}{100}\right)=\frac{3}{2}.\frac{99}{100}=\frac{297}{200}\)

Cảm ơn bạn

mik có hc lazi nè
