Gỉai giúp t bài này với ạ mơn các c rất nhiều ạ giải chi tiết giùm t với ạ t mơn nhìu ạ
tính: (2^17+5^17)(3^14-5^12)(2^4-4^2)/15^2+5^3+67^7
1im cac so tu nhien x,y biet:
1. 252/x=84/97
2.x-2/255=114/153
3.50/19 nhan38/25<x<69/17+33/17
4.7/15<x/40<8/15
5.(1 1/4 -3/5):17/20<x/17<(5 1/3-3 1/2):12/17
6.y/15=2/5
7.3/x-7=27/135
help me
Gỉai giúp t bai nay vs nhé . Cảm ưn nhìu
