Ответ:

а) \(\sqrt{144}+5\sqrt{0.64}=12+5\cdot0.8=16\).

б) \((4\sqrt2)^8=((4\sqrt2)^2)^4=32^4=1\,048\,576\).

в) \(\sqrt{0.16\cdot25}-6\sqrt{\frac{1}{36}}=\sqrt4-6\cdot\frac16=2-1=1\).

а) \(4\sqrt{0.81}+\sqrt{196}=4\cdot0.9+14=17.6\).

б) \((3\sqrt7)^2=9\cdot7=63\).

в) \(\sqrt{0.04\cdot81}-7\sqrt{\frac{1}{49}}=\sqrt{3.24}-7\cdot\frac17=1.8-1=0.8\).
