\(E=1+2+2^2+...+2^{2022}\)

=>\(2E=2+2^2+2^3+...+2^{2023}\)

=>\(2E-E=2+2^2+...+2^{2023}-1-2-...-2^{2022}\)

Gọi số học sinh khối 6 là x(bạn)

(Điều kiện: \(x\in Z^+\))

Vì số học sinh nằm trong khoảng từ 350 đến 400 nên \(x\in\left\{350;351;...;400\right\}\)

Số học sinh này khi xếp thành hàng 10 thì dư 5 bạn nên x có chữ số tận cùng là 5

mà 350<=x<=400

nên \(x\in\left\{355;365;375;385;395\right\}\)

Số học sinh khi xếp thành hàng 8 thì dư 3 bạn 

mà \(x\in\left\{355;365;375;385;395\right\}\)

nên \(x\in\left\{355;395\right\}\)

Số học sinh khi chia thành mỗi hàng 12 bạn thì dư 9 bạn nên x=395(nhận)

vậy: Số học sinh khối 6 là 395 bạn

Trong mp(SAD) qua G dựng đường thẳng d//AD

HA=HB; KC=KD => HK là đường trung bình của hình thang ABCD

=> HK//AD và \(HK=\dfrac{AB+CD}{2}\)

Ta có d//AD

=> d//HK (cùng // với AD)

\(\Rightarrow d\in\left(GHK\right)\) mà \(d\in\left(SAD\right)\) => d là giao tuyến của (SAD) với (GHK)

Xét tg SAE có MN//AD \(\Rightarrow\dfrac{SM}{SA}=\dfrac{MG}{AE}=\dfrac{SG}{SE}=\dfrac{2}{3}\)

Xét tg SAD có MN//AD \(\Rightarrow\dfrac{MN}{AD}=\dfrac{SM}{SA}=\dfrac{2}{3}\Rightarrow MN=\dfrac{2}{3}AD\)

Do MNHK là hbh => MN=HK

\(\Rightarrow\dfrac{2}{3}AD=\dfrac{AD+BC}{2}\Leftrightarrow4AD=3AD+3BC\)

\(\Leftrightarrow AD=3BC=k.BC\Rightarrow k=3\)
