Giúp em nha m.n

Answer 2

\(=\dfrac{9}{25}-\dfrac{1}{9}+16\cdot\dfrac{1}{4}-1=\dfrac{9}{25}-\dfrac{1}{9}+3=\dfrac{731}{225}\)

Answer 3

\(\text{b)}\left(\dfrac{3}{5}\right)^2-\left[\dfrac{1}{3}:3-\sqrt{16}.\left(\dfrac{1}{2}\right)^2\right]-\left(10.12-2014\right)^0\)

\(=\dfrac{9}{25}-\left[\dfrac{1}{9}-1\right]-1\)

\(=\dfrac{9}{25}-\left(\dfrac{-8}{9}\right)-1\)

\(=\dfrac{281}{225}-1\)

\(=\dfrac{56}{225}\)
