Explicação passo-a-passo:

$\sqrt{36} \times (0.7 - \frac{1}{5}) + \frac{3}{5} \\ \\ \sqrt{36}(0.7 - \frac{1}{5}) + \frac{3}{4} \\ \\ 6 \times 6 \\36 \\ \sqrt{36}(0.7 - \frac{1}{5}) + \frac{3}{4}\\ \\ 6(0.7 - \frac{1}{5}) + \frac{3}{4} \\ \\0.7 - \frac{1}{5} \\ \\ \frac{25}{5} \\ \\6(0.7 - \frac{1}{5}) + \frac{3}{4} \\ \\6 \times \frac{2.5}{5} + \frac{3}{4} \\ \\ \frac{6 \times 2.5}{5} + \frac{3}{4} \\ \\6.25 \\ 15 \\ \\ 6 \times \frac{25}{5} + \frac{3}{4}\\ \\ \frac{15}{5} + \frac{3}{4} \\ \\ \frac{15}{5}\\ \\ 3 \\ \\ \frac{15}{5} + \frac{3}{4} \\ \\ 3 + \frac{3}{4} \\ \\ \frac{15}{4} \\ resposta \\ \frac{15}{4} \\ na \: forma \: decimal \\ 3.75$
