Question

alguem ai me ajuda

Answer 1

                   $\frac{(0,3+ \frac{1}{5} )^2}{ \sqrt{ \frac{9}{16} } } \\ \\ = \frac{(0,3 +0,2)^2}{ \frac{3}{4} } \\ \\ =\frac{(0,5)^2}{ \frac{3}{4} } \\ \\ = \frac{0,25}{ \frac{3}{4} } \\ \\ = \frac{ \frac{1}{4} }{ \frac{3}{4} } \\ \\ = \frac{1x4}{3x4} \\ \\ = \frac{1}{3}$

Answer 2

$\dfrac{\left(0,3+\frac{1}{5} \right )^{2}}{\sqrt{\frac{9}{16}}}\\ \\ =\dfrac{\left(\frac{3}{10}+\frac{1}{5} \right )^{2}}{\frac{\sqrt{9}}{\sqrt{16}}}\\ \\ =\dfrac{\left(\frac{3}{10}+\frac{2}{10} \right )^{2}}{\frac{3}{4}}\\ \\ =\dfrac{\left(\frac{3+2}{10} \right )^{2}}{\frac{3}{4}}\\ \\ =\dfrac{\left(\frac{5}{10} \right )^{2}}{\frac{3}{4}}\\ \\ =\dfrac{25}{100}\cdot \dfrac{4}{3}\\ \\ =\dfrac{25\cdot 4}{100\cdot 3}\\ \\ =\dfrac{\diagup\!\!\!\!\!\!\! 100}{\diagup\!\!\!\!\!\!\! 100\cdot 3}\\ \\ =\dfrac{1}{3}$
