Пошаговое объяснение:

1)

[tex]10000x + 0.01y[/tex]

Якщо x=5432; y=459800

[tex]10000x + 0.01y = \\ = 10000 \times 5432 + 0.01 \times \\ \times 459800 = \\ = 54320000 + 4598 = \\ = 54324598[/tex]

2)

[tex](42.8 - 3 - 5.71x) + \\ + (31.7x \div 2.5y) [/tex]

Якщо x = 2; y = 2

[tex](42.8 - 3 - 5.71 \times 2) + \\ + (31.7 \times 2 \div 2.5 \times 2) = \\ = (42.8 - 3 - 5.71 \times 2) + \\ + ( \frac{31.7 \times 2}{2.5 \times 2} ) = \\ = (42.8 - 3 - 5.71 \times 2) + \\ + ( \frac{31.7}{2.5} ) = \\ = (42.8 - 3 - 5.71 \times 2) + (31.7 \div 2.5) = \\ = (42.8 - 3 - 11.42) + 12.68 = \\ = 28.38 + 12.68 = \\ = 41.06[/tex]
