Question

(\frac{3}{5})^{2} +(-\frac{1}{2} )^{2} =

Answer 1

Resposta:

$\frac{11}{20}$

Cálculo :

$\\ (\frac{ \: \:3 {}^{} }{5}) {}^{2} + ( - \frac{ \: 1 {}^{} }{2} {}^{} ) {}^{2} \\ \\ ( \frac{3}{5} \times \frac{3}{5} ) + ( - \frac{1}{2} \: \times - \frac{1}{2}^{} ) {}^{( - \times - = + )} \\ \\ \frac{9}{25} + \frac{1}{4} \\ \frac{}{}$

MMC de 25 e 4 = 100

$\frac{36 - 25}{100} = \frac{11}{20}$
