Answer:

$a.\frac{4}{49}\\b.\frac{81}{100} \\c.\frac{841}{2601} \\d.\frac{25}{169}$

Step-by-step explanation:

$a.(\frac{2}{7} )^{2} \\=\frac{2}{7}* \frac{2}{7}\\=\frac{4}{49} \\\\b.(\frac{-9}{10} )^{2} \\=\frac{-9}{10}*\frac{-9}{10}\\=\frac{81}{100} \\\\c.(\frac{29}{51} )^{2} \\=\frac{29}{51}*\frac{29}{51}\\=\frac{841}{2601} \\\\d.(\frac{-5}{13} )^{2} \\=\frac{-5}{13} *\frac{-5}{13} \\=\frac{25}{169}$
