Answer 1

Ответ:

Пошаговое объяснение:

1) 3m•(-2,1) = -6,3m

2) 3,6•(-5x) = -18x

3)10m•(-1,7)•n = -17mn

4)-7a•3b•(-6c) = 126abc

5)16x•(8. b)•45 k = не пойму, что после 8.?

6)-0,2t•(-5a)•(-b) = -1tab

Answer 2

It seems like you've provided a list of expressions involving scalar multiplication of vectors and terms. To simplify these expressions, I'll perform the scalar multiplication where applicable. Remember that scalar multiplication involves multiplying each component of the vector or term by the given scalar. Here are the results:

1. 3m • (-2, 1) Result: (-6m, 3m)

2. 3,6 • (-5x) Result: (-18x)

3. 10m • (-1, 7) • n Result: (-10mn, 70mn)

4. -7a • 3b • (-6c) Result: 126abc

5. 16x • (8, b) • 45k Result: (1280xk, 45bk)

6. 646 • (-0,2t) • (-5a) • (-b) Result: 64.6tab

If you have any other expressions or need further assistance, feel free to ask!
