\(C=7-\left(-\dfrac{4}{5}\right)^0+\left(\dfrac{1}{3}\right)^2:2\\ =7-1+\dfrac{1}{9}.\dfrac{1}{2}\\ =6+\dfrac{1}{18}=\dfrac{109}{18}\)
\(C=7-\left(-\dfrac{4}{5}\right)^0+\left(\dfrac{1}{3}\right)^2:2\)
\(=7-1+\dfrac{1}{9}:2\)
\(=6+\dfrac{1}{18}=\dfrac{108}{18}+\dfrac{1}{18}=\dfrac{109}{18}\)
\(C=7-\left(-\dfrac{4}{5}\right)^0+\left(\dfrac{1}{3}\right)^2:2\)
\(C=7-1+\dfrac{1}{9}:2\)
\(C=6+\dfrac{1}{9}.\dfrac{1}{2}\)
\(C=6+\dfrac{1}{18}\)
\(C=\dfrac{109}{18}\)
