Question

\(-\dfrac{10}{21}.\left[\dfrac{9}{15}+\left(\dfrac{3}{5}\right)^2\right]\)

Answer 1

\(-\dfrac{10}{21}\cdot\)[\(\dfrac{9}{15}+\left(\dfrac{3}{5}\right)^2\) ]

\(=\)\(-\dfrac{10}{21}\cdot\left(\dfrac{9}{15}+\dfrac{9}{25}\right)\)

\(=\)\(-\dfrac{10}{21}\cdot\dfrac{24}{25}\)

\(=-\dfrac{16}{35}\)

Answer 2

Answer 3

\(=-\frac{10}{21}\times(\frac{9}{15}+\frac{9}{25})\)

\(=-\frac{10}{21}\times\frac{24}{25}\)

\(=\frac{16}{35}\)
