mn giúp e vs ạ ......e cảm ơn

\(1,\left|\dfrac{-2}{5}-\dfrac{1}{2}\right|+\dfrac{-3}{5}-\dfrac{3^2}{20}\)
2, \(\left(1+\dfrac{2}{3}-\dfrac{14}{9}\right):\left(\dfrac{5}{6}-\dfrac{4}{5}\right)^2\)

Bài 1 : So sánh:
a, \(5^{36}\) và \(11^{24}\)
b, \(3^{2n}\) và \(2^{3n}\) với n là số tự nhiên
c, \(5^{23}\) và \(6.5^{22}\)
d, \(7.2^{13}\) và \(2^{16}\)
e, \(2^{332}\) và \(3^{223}\)
f, \(21^{15}\)và \(27^5.49^8\)
Bài 2 : Tính
a, 1+2+3+4+...+100
b, 1+3+5+7+...+99
c, 2+4+6+8+...+200
d, 3+7+11+...+79

Bài 1: Thực hiện phép tính:
1, \(\dfrac{3}{2}-\left|\dfrac{-1}{12}\right|-\left(2-\dfrac{1}{3}\right)^2\)
2, \(\left(\dfrac{2}{3}-0,25\right).\left(\dfrac{-2}{5}\right)^2-\left(1\dfrac{2}{5}+1\dfrac{1}{3}-2\right)\)
3, \(\left(\dfrac{-1}{3}\right)^2-\dfrac{1}{12}+\left|\dfrac{-5}{18}\right|\)
\(4,\left|\dfrac{-2}{5}-\dfrac{1}{2}\right|+\dfrac{-3}{5}-\dfrac{3^2}{20}\)
5, \(\left(1+\dfrac{2}{3}-\dfrac{14}{9}\right):\left(\dfrac{5}{6}-\dfrac{4}{5}\right)^2\)
