a) $$0.4^2 \cdot 10 = 0.16 \cdot 10 = 1.6$$
б) $$0.3^3 \cdot 100 = 0.027 \cdot 100 = 2.7$$
в) $$0.1^4 + 0.1^2 = 0.0001 + 0.01 = 0.0101$$
г) $$2^2 \cdot 0.2^2 = 4 \cdot 0.04 = 0.16$$
б) $$97.2y - 17.2y + 9.2 - 97.3 = 80y - 88.1$$
д) $$1.7^2 \cdot 100 = 2.89 \cdot 100 = 289$$
e) $$0.4^2 + 0.8^2 - 0.2 = 0.16 + 0.64 - 0.2 = 0.8 - 0.2 = 0.6$$
