Answer 2

h: \(=-\left(\dfrac{1}{9}\cdot9\right)^{25}-\dfrac{2}{3}\cdot4=-1-\dfrac{8}{3}=-\dfrac{11}{3}\)

d: \(=\dfrac{7}{5}\left(23+\dfrac{1}{4}-13-\dfrac{1}{4}\right)=\dfrac{7}{5}\cdot10=14\)

a: \(=\left(\dfrac{11}{24}+\dfrac{13}{24}\right)-\left(\dfrac{5}{41}+\dfrac{36}{41}\right)+\dfrac{1}{2}=\dfrac{1}{2}\)

b: \(=-12:\left(\dfrac{18-20}{24}\right)^2\)

\(=-12:\left(-\dfrac{1}{12}\right)^2\)

\(=-12\cdot144=-1368\)
