Question

Y=(10-5x^4)*(2x^3-9cosx+1)

Answer 1

$y = - 80$

Пошаговое объяснение:

$y = (10 - 5 \times 0 {}^{4} ) \times (2 \times 0 {}^{3} - 9 \cos(0) + 1)$

$y = (10 - 5 \times 0) \times (2 \times 0 - 9 \cos(0) + 1)$

$y = (10 - 5 \times 0) \times (2 \times 0 - 9 \times 1 + 1)$

$y = (10 - 5 \times 0) \times (2 \times 0 - 9 + 1)$

$y = (10 - 0) \times (2 \times 0 - 9 + 1)$

$y = (10 - 0) \times (0 - 9 + 1)$

$y = 10 \times (0 - 9 + 1)$

$y = 10 \times ( - 9 + 1)$

$y = 10 \times ( - 8)$

$y = - 80$
