Answer 1

Explicación paso a paso:

$a = ( \frac{1}{4} ) ^{2} + ( { \frac{3}{4} })^{2} \\ a = \frac{1}{16} + \frac{9}{16} \\ a = \frac{5}{8}$

$b = ( \sqrt{ \frac{9}{36} } ) \times ( \sqrt{ \frac{100}{49} } ) \\ b = \sqrt{ \frac{1}{4} } \times \ \sqrt{ \frac{100}{49} } \\ b = \frac{1}{2} \times \frac{10}{7} \\ b = \frac{5}{7}$

Lo que piden :

$a + b = \frac{5}{8} + \frac{5}{7 } = \frac{75}{56}$
