Answer 2

Problema 1:

$\:\left(0,\:3\right)^2\:\:\:+\:\sqrt{0,\:81}+\left(0,\:2\right)^2\:+\:2,\:1\:=\\\\= 0.3^2+\sqrt{0.81}+0.2^2+2.\\\\= 0.09+\sqrt{0.81}+0.2^2+2.1\\\\= 0.09+0.9+0.2^2+2.1\\\\= 0.09+0.9+0.04+2.1\\\\= 3.13$

Problema 2:

$3\cdot \sqrt{0,\:16}\cdot \left(0,\:2\right)+4,\:5 =\\\\= 3\sqrt{0.16}\cdot \:0.2+4.5\\\\= 0.6\sqrt{0.16}+4.5\\\\= 0.24+4.5\\\\= 4.74$

Problema 3:

$\left(0,\:5\right)^2\:+\sqrt{\frac{36}{9}}\:+\left(0,\:02\right)^2-0,\:15 =\\\\= 0.5^2+\sqrt{\frac{36}{9}}+0.02^2-0.15\\\\ =0.5^2+2+0.02^2-0.15\\\\= 0.5^2+0.02^2+1.85\\\\= 0.25+0.0004+1.85\\\\= 2.1004$

Problema 4:

$\left(0,\:1\right)^3+\sqrt{1,\:44}+\left(0,\:3\right)^2+4,\:5 =\\\\= 0.1^3+\sqrt{1.44}+0.3^2+4.5\\\\= 0.001+\sqrt{1.44}+0.3^2+4.5\\\\= 0.001+1.2+0.3^2+4.5\\\\= 0.001+1.2+0.09+4.5\\\\= 5.791$
