b, \(5\cdot\left|x-\dfrac{2}{3}\right|-\dfrac{1}{2}=\dfrac{7}{3}\)

\(5\cdot\left|x-\dfrac{2}{3}\right|=\dfrac{17}{6}\)

\(\left|x-\dfrac{2}{3}\right|=\dfrac{17}{30}\)

\(\Rightarrow x-\dfrac{2}{3}=\dfrac{17}{30};x-\dfrac{2}{3}=\dfrac{-17}{30}\)

\(\Rightarrow x\in\left\{\dfrac{37}{30};\dfrac{1}{10}\right\}\)

c, \(8\cdot\left(x-\dfrac{3}{4}\right)^3=125\)

\(\left(x-\dfrac{3}{4}\right)^3=\dfrac{125}{8}\)

\(x-\dfrac{3}{4}=\dfrac{5}{2}\)

\(x=\dfrac{13}{4}\)

2. a, \(3\cdot\left(2x-\dfrac{1}{2}\right)=\dfrac{27}{49}\)

\(2x-\dfrac{1}{2}=\dfrac{9}{49}\)

\(2x=\dfrac{67}{98}\)

\(x=\dfrac{67}{196}\)

1. a, Ta có: \(2^{24}=2^{3^8}=8^8\)

Lại có: \(3^{16}=3^{2^8}=9^8\)

Vì \(8^8< 9^8\Rightarrow2^{24}< 3^{16}\)

b, Ta có: \(5^{300}=5^{3^{100}}=125^{100}\)

Lại có: \(3^{500}=3^{5^{100}}=243^{100}\)

Vì \(125^{100}< 243^{100}\Rightarrow5^{300}< 3^{500}\)

c, Ta có: \(2^{700}=2^{7^{100}}=128^{100}\)

Lại có: \(5^{300}=5^{3^{100}}=125^{100}\)

Vì \(128^{100}>125^{100}\Rightarrow2^{700}>5^{300}\)

d, Ta có: \(2^{400}=2^{2^{200}}=4^{200}\)

\(\Rightarrow2^{400}=4^{200}\)

e, Ta có: \(99^{20}=99^{2^{10}}=9801^{10}\)

Vì \(9801^{10}< 9999^{10}\Rightarrow99^{20}< 9999^{10}\)
