Answer 1

[tex] \sqrt{0.08} * \sqrt{2} = \sqrt{0.16} = \sqrt{ \frac{4}{25} } = \frac{2}{5} \\ \\ 3 \sqrt{ 1\frac{11}{25} } - 1 = 3 \sqrt{ \frac{36}{25} } - 1 = 3* \frac{6}{5} - 1 = \frac{18}{5} - 1 = \frac{13}{5} = 2 \frac{3}{5} \\ \\ (2 \sqrt{3} - \sqrt{27} )* \sqrt{ 3} = (2 \sqrt{3} - 3 \sqrt{3} ) \sqrt{3} = - \sqrt{3} * \sqrt{3} = - 3 \\ \\ (√5 - 2√2)² = 5 - 4√10 + 8 = 13 - 4√10
