\(\frac{3^2}{\left(0,375\right)^2}=\frac{9}{0,140625}=64\)
\(\frac{3^2}{\left(0,375\right)^2}=\frac{3^2}{\left(\frac{3}{8}\right)^2}=3^2:\left(\frac{3}{8}\right)^2=3^2:\frac{3^2}{8^2}=3^2.\frac{8^2}{3^2}=8^2=64\)
\(\frac{3^2}{\left(0,375\right)^2}\)
\(=\frac{3^2}{\left(\frac{3}{8}\right)^2}\)
\(=3^2:\left(\frac{3}{8}\right)^2\)
\(=3^2:\frac{3^2}{8^2}\)
\(=3^2\times\frac{8^2}{3^2}\)
\(=8^2\)
\(=64\)
