Question

Пожалуйста помогите ​

Answer 1

а)

${3}^{2} + {0.2}^{2} = 9 + \frac{1}{25 } = \frac{226}{25}$

б)

$(3 + 0.2)^{2} = 3.2^{2} = \frac{256}{25}$

в)

$(3 + 0.2)( {3}^{2} - 3 \times 0.2 + {0.2}^{2} ) = 3.2 \times \frac{76}{25} = \frac{1216}{125}$

г)

${3}^{3} + 3 \times 9 \times 0.2 + 3 \times 3 \times \frac{1}{25} + {0.2}^{3} = 9 + 5.4 + \frac{9}{25} + \frac{1}{125} = \frac{1846}{125}$
