\(a,L=5100\left(A^o\right)\)
\(\Rightarrow N=\dfrac{2L}{3,4}=3000\left(nu\right)\)
\(10\%N=300\left(nu\right)\)
Theo bài và NTBS ta có hệ: \(\left\{{}\begin{matrix}A+G=1500\\A-G=300\end{matrix}\right.\rightarrow\left\{{}\begin{matrix}A=T=900\left(nu\right)\\G=X=600\left(nu\right)\end{matrix}\right.\)
\(b,\) \(A_{mt}=T_{mt}=A.\left(2^5-1\right)=27900\left(nu\right)\)
\(G_{mt}=X_{mt}=G.\left(2^5-1\right)=18600\left(nu\right)\)
