Cm:(3525-3524)\(⋮\)17
Ta có: \(35^{25}-35^{24}\)
\(=35^{24}\cdot\left(35-1\right)\)
\(=35^{24}\cdot34\)
Mà: 34 ⋮ 17
\(\Rightarrow35^{24}\cdot34\) ⋮ 17
Hay \(35^{25}-35^{24}\) ⋮ 17 (đpcm)
\(\left(35^{25}-35^{24}\right)=\left(35.35^{24}-35^{24}\right)=34.35^{24}\)
mà \(34⋮17\)
\(\Rightarrow34.35^{24}⋮17\)
