Answer 1

a) \(10\sqrt{0,01}.\sqrt{\frac{16}{9}}+3\sqrt{49}-\frac{1}{6}\sqrt{4}\)

\(=10\sqrt{\frac{10}{100}}.\sqrt{\frac{4^2}{3^2}}+3.\sqrt{7^2}-\frac{1}{6}\sqrt{2^2}\)

\(=10.\frac{\sqrt{10}}{10}.\frac{4}{3}+3.7-\frac{1}{6}.2\)

\(=\frac{4\sqrt{10}}{3}+27-\frac{1}{3}\)

\(=\frac{4}{3}\sqrt{10}+\frac{80}{3}\)

b) \(\left(1+\frac{2}{3}-\frac{1}{4}\right).\left(0,8-\frac{3}{4}\right)^2\)

\(=\frac{17}{12}.\left(\frac{4}{5}-\frac{3}{4}\right)^2\)

\(=\frac{17}{12}.\left(\frac{1}{20}\right)^2\)

\(=\frac{17}{12}.\frac{1}{400}\)

\(=\frac{17}{4800}\)

Answer 2

a.\(\frac{133}{6}\)

b.\(\frac{17}{4800}\)
