Answer 1

Answer:

3k^3 + k^2 - 4k

Step-by-step explanation:

k * 3k^2 = 3k^3

k * k = k^2

k * -4 = -4k

3k^3 + k^2 - 4k

Answer 2

Answer:

$-4k + {k}^{2} + 3 {k}^{3}$

Step-by-step explanation:

According to the Product-to-Power Exponential Rule, whenever you divide terms with exponents and coefficients, you add the exponents:

k[3k² + k - 4]

3k³ + k² - 4k

The above answer is written in reverse, but it is the exact same result.
