Question

\(\frac{\sqrt{81}}{25}.\frac{11}{5}+\left(\frac{-3}{2}\right)^2.\frac{14}{5}\)

Answer 1

\(\frac{\sqrt{81}}{25}.\frac{11}{5}+\left(\frac{-3}{2}\right)^2.\frac{14}{5}\)=\(\frac{9}{25}.\frac{11}{5}+\frac{9}{4}.\frac{14}{5}\)

=\(\frac{99}{125}\)+\(\frac{63}{10}\)

=.... (bn tự tính nha)

Answer 2

\(\frac{\sqrt{81}}{25}.\frac{11}{5}+\left(-\frac{3}{2}\right)^2.\frac{14}{5}\)

\(=\frac{9}{15}.\frac{11}{5}+\frac{9}{4}.\frac{14}{5}\)

\(=\frac{33}{25}+\frac{63}{10}\)

\(=\frac{381}{50}\)
