\(\text{b)}\left(\dfrac{3}{5}\right)^2-\left[\dfrac{1}{3}:3-\sqrt{16}.\left(\dfrac{1}{2}\right)^2\right]-\left(10.12-2014\right)^0\)
\(=\dfrac{9}{25}-\left[\dfrac{1}{9}-1\right]-1\)
\(=\dfrac{9}{25}-\left(\dfrac{-8}{9}\right)-1\)
\(=\dfrac{281}{225}-1\)
\(=\dfrac{56}{225}\)
\(\text{c)}5\sqrt{\dfrac{1}{25}}-3\sqrt{\dfrac{1}{9}}\)
