Question

Упростите 1) 5a(a2-6a4+3) 2) x+43x-2 3)6m+5n7m-3n​

Answer 1

Объяснение:

1)

$5a(a {}^{2} - 6a {}^{4} + 3) = 5a {}^{3} - 30a {}^{5} + 15a = - 30a {}^{5} + 5a {}^{3} + 15a$

2)

$x + 43x - 23 = 1x + 43x - 23 = (1 + 43)x - 23 = 44x - 23$

3)

$6m + 5n {}^{7} m - 3n = 6m + 5mn {}^{7} - 3n$
