17+3= bao nhieu
56,65:17= bao nhieu
so tu nhien a chia 17 du 11 chia 23 du 18 chia 11du 3.hoinchia 4301 du bao nhieu
ta có a-11 chia hết cho 17;a-18 chia hết cho 23;a-3 chia hết cho 11
<=>a-198chia hết cho 17,23,11
a-198 chia hết cho 17 x 23 x11=4301
=>a chia 4301 dư 198 (đpcm)

vậy tần cùng của 17^1000 là 1
Ta có: \(17^{1000}=\left(17^4\right)^{250}=\left(........1\right)^{250}=..........1\)
Vậy,chữ số tận cùng của \(17^{1000}\) bằng 1
11-11-17+563×63627 bang bao nhieu
11-11-17+563x63 627
=11-11-17+35 822 001
=-17+35 822 001
=35 821 984
11-11-17+563*63627= 37 740 342

Tinh bang cach thuan tien 9/5:17/15+8/5:17/15 bang bao nhieu
\(\frac{9}{5}:\frac{17}{15}+\frac{8}{5}:\frac{17}{15}\)
\(=\frac{17}{15}:\left(\frac{9}{5}+\frac{8}{5}\right)\)
\(=\frac{17}{15}:3\)
\(=\frac{17}{45}\)
\(\frac{9}{5}:\frac{17}{15}+\frac{8}{5}:\frac{17}{5}=\frac{9}{5}.\frac{15}{17}+\frac{8}{5}.\frac{15}{17}=\frac{15}{17}\left(\frac{9}{5}+\frac{8}{5}\right)=\frac{15}{17}.\frac{17}{5}=3\)
9/5 : 17/15 + 8/5 : 17/15
= ( 9/5 + 8/5 ) x 15/17
= 17/5 x 15/17
= 3
