Question

Answer 1

i: \(\sqrt{64}+2\cdot\sqrt{\left(-3\right)^2}-7\cdot\sqrt{1,69}+3\cdot\sqrt{\frac{25}{16}}\)

\(=8+2\cdot6-7\cdot1,3+3\cdot\frac54\)

=8+12-9,1+3,75

=14,65

k: \(10\cdot\sqrt{0,01}\cdot\sqrt{\frac{16}{9}}+3\cdot\sqrt{49}-\frac16\cdot\sqrt4\)

\(=10\cdot0,1\cdot\frac43+3\cdot7-\frac16\cdot2\)

\(=\frac43-\frac13+21=21+1=22\)
