Question

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

Trần Minh Anh · Accepted Answer

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

=$\frac{99}{125}$+$\frac{63}{10}$

=.... (bn tự tính nha)

Trần Nguyễn Bảo Quyên · Answer

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

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

$=\frac{33}{25}+\frac{63}{10}$

$=\frac{381}{50}$

Câu trả lời:

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

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

$=\frac{33}{25}+\frac{63}{10}$

$=\frac{381}{50}$
