\(\dfrac{1}{x}+\dfrac{1}{y}=\dfrac{1}{3}\)
\(\dfrac{x+y}{xy}=\dfrac{1}{3}\)
\(3\left(x+y\right)=xy\)
\(xy-3x-3y=0\)
\(xy-3x-3y+9=9\)
\(x\left(y-3\right)-3\left(y-3\right)=9\)
\(\left(x-3\right)\left(y-3\right)=9\)
Ta có bảng sau:
| x-3 | -9 | -3 | -1 | 1 | 3 | 9 |
| y-3 | -1 | -3 | -9 | 9 | 3 | 1 |
| x | -6 | 0 (loại) | 2 | 4 | 6 | 12 |
| y | 2 | 0 (loại) | -6 | 12 | 6 | 4 |
Vậy \(\left(x;y\right)=\left(-6;2\right);\left(2;-6\right);\left(4;12\right);\left(6;6\right);\left(12;4\right)\)
\(10M=\dfrac{10.\left(10^{100}+1\right)}{10^{101}+1}=\dfrac{10^{101}+10}{10^{101}+1}=\dfrac{10^{101}+1+9}{10^{101}+1}=1+\dfrac{9}{10^{101}+1}\)
\(10N=\dfrac{10.\left(10^{101}+1\right)}{10^{102}+1}=\dfrac{10^{102}+10}{10^{102}+1}=\dfrac{10^{102}+1+9}{10^{102}+1}=1+\dfrac{9}{10^{102}+1}\)
Do \(10^{101}< 10^{102}\Rightarrow10^{101}+1< 10^{102}+1\)
\(\Rightarrow\dfrac{9}{10^{101}+1}>\dfrac{9}{10^{102}+1}\)
\(\Rightarrow1+\dfrac{9}{10^{101}+1}>1+\dfrac{9}{10^{102}+1}\)
\(\Rightarrow10M>10N\)
\(\Rightarrow M>N\)
a) Mạch bổ sung: GCATCAGTGCT
b) Trình tự gene:
Mạch 1: CGTAGTCACGA
Mạch 2: GCATCAGTGCT
c) Số nucleotide của gene A = T = 5 → Số nucleotide môi trường cần cung cấp khi nhân đôi 5 lần = 5 x (25 -1) = 155.
Số nucleotide của gene G = C = 6 → Số nucleotide môi trường cần cung cấp khi nhân đôi 5 lần = 6 x (25 -1) = 186.
