Qua G, kẻ mn//a//b

mn//a
=>góc G1=góc A1(hai góc so le trong)
=>góc G1=42 độ
mn//b
=>góc G2+góc B2=180 độ(trong cùng phía)
=>góc G2=180-138=42 độ
=>góc AGB=42+42=84 độ
a) \(4\times\dfrac{1}{4^2}+25\times\left[\dfrac{3^3}{4^3}:\dfrac{5^3}{4^3}\right]:\dfrac{3^3}{2^3}\)
\(=\dfrac{1}{4}+5^2\times\dfrac{3^3}{4^3}\times\dfrac{4^3}{5^3}\times\dfrac{2^3}{3^3}\)
\(=\dfrac{1}{4}+\dfrac{2^3}{5}=\dfrac{1}{4}+\dfrac{8}{5}=\dfrac{37}{20}\)
b) \(2^3+3\times\left(\dfrac{1}{2}\right)^{0-1}+\left[\left(-2\right)^2:\dfrac{1}{2}\right]-8\)
\(=8+3\times\left(2^{-1}\right)^{-1}+2^2\times2-8\)
\(=3\times2+2^3=14\)
