\(a,A=2024=2^3\times11\times23\\B=8^5\times 125^6=\left(2^3\right)^5\times\left(5^3\right)^6=2^{15}\times5^{18}\\ b,Ư\left(84\right)=\left\{1;2;3;4;6;7;12;14;21;28;42;84\right\}\\\Rightarrow x\in\left\{1;2;3;4;6;7;12;14;21;28;42;84\right\}\\ x\in B\left(21\right)=\left\{0;21;42;63;84;105;126;147;168;189;210;....\right\}\)
a) 60 = 22 . 3 . 5; b) 64 = 26; c) 285 = 3 . 5 . 19;
d) 1035 = 32 . 5 . 23; e) 400 = 24 . 52; g) 1000000 = 26 . 56
a/ \(60=2^2.3.5\)
b/ \(84=2^2.3.7\)
c/ \(285=3.5.19\)
d/ \(1035=3^2.5.23\)
e/ \(400=2^4.5^2\)
g/ \(1000000=2^6.5^6\)
\(110=2\cdot5\cdot11\)
\(250=2\cdot5^3\)
\(340=2^2\cdot5\cdot17\)
\(1500=2^2\cdot3\cdot5^3\)
\(280=2^3\cdot5\cdot7\)
\(760=2^3\cdot5\cdot19\)
110=2.5.11
340=\(2^2\).5.17
250=2.\(5^3\)
1500=\(2^2\).5.\(5^3\)
280=\(2^3\).5.7
760=\(2^3\).5.19
hok tốt.
ta có :
\(110=11.10=11.2.5\)
\(250=25.10=5^2.2.5=2.5^3\)
\(340=34.10=17.2.2.5=2^2.5.17\)
\(1500=15.100=3.5.2^2.5^2=2^2.3.5^3\)
\(280=28.10=7.2^2.2.5=2^3.5.7\)
\(760=76.10=19.2^2.2.5=2^3.5.19\)
a: \(180=2^2\cdot3^2\cdot5\)
b: \(2034=2\cdot3^2\cdot113\)
c: \(1500=2^2\cdot3\cdot5^3\)
d: \(4000=2^5\cdot5^3\)
e: \(504=2^3\cdot3^2\cdot7\)
a) 180 = 2².3².5
b) 2034 = 2.3².113
c) 1500 = 2².3.5³
d) 4000 = 2⁵.5³
e) 504 = 2³.3².7
