Question

1 ) -a4×5; 2 ) 8b×(-3); 3 ) (-5c)×2;

Answer 1

1) (если a^4)- -5a^4
(Если 4a)- -20a
2) -24b
3) -10c

Answer 2

1. -a4 × 5: This expression can be simplified by multiplying -a4 by 5. However, the term "a4" is not clear. If you meant "-a" multiplied by 4, then the expression becomes:

-4a × 5 = -20a

2. 8b × (-3): In this expression, you are multiplying 8b by -3. The result is obtained by multiplying the coefficients and keeping the variable unchanged:

8b × (-3) = -24b

3. (-5c) × 2: In this expression, you are multiplying -5c by 2. Similar to the previous example, multiply the coefficients and keep the variable unchanged:

(-5c) × 2 = -10c

So, the simplified expressions are:

1. -a4 × 5 = -20a
2. 8b × (-3) = -24b
3. (-5c) × 2 = -10c
