1 tim x 254÷x=14(du16) lam thanh bai nhe
254:x=14(dư16)
(254-16):x=14
238 :x=14
x=238:14=17
Vậy x=17
tim x: 254:x = 14 [du 16]
254:x = 14 [du 16]
x = (254-16):14
x = 17
tim so tu nhien n sao cho n :17 du 8 ,n: 25 du16
Vì n chia cho 17 dư 8 \(\Rightarrow n+9⋮17\)
Vì n chia cho 25 dư 16 \(\Rightarrow n+9⋮25\)
\(\Rightarrow n+9\in BC\left(17;25\right)\)
Ta có:
\(17=17\)
\(25=5^2\)
\(\Rightarrow BCNN\left(17;25\right)=17.5^2=425\)
\(\Rightarrow BC\left(17;25\right)=B\left(425\right)=\left\{0;425;850;1275;...\right\}\)
\(\Rightarrow n+9\in\left\{0;425;850;1275;...\right\}\)
\(\Rightarrow n\in\left\{416;841;1266;...\right\}\)
Vậy \(n\in\left\{416;841;1266;...\right\}\)
ta có
17 + 8 = 25
25 + 16 = 41
vậy n = 41

a) Tìm x 254 : x = 14 (dư 16)
Ta có:
\(254=14x+16\\ \Rightarrow14x=238\\ \Rightarrow x=17\)
Tìm X 254:X=14(dư 16)
Ta có: 254:x=14(dư 16)
=> (254-16) : x = 14
=> 238 : x = 14
=> x = 238 : 14
=> x = 17
Vây x = 17
254:x=14(dư16)
254:x=14(dư16)
254 : X = 14 ( dư 16 )
Vậy: 254 = 14 x X + 16
254 - 16 = 14 x X
238 = 14 x X
x = 238 : 14
x = 17
tick nhé bạn ơi cầu xin bạn đấy huhuhu
