Answer 1

`-4k + {k}^(2) + 3 {k}^(3)`

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.

Answer 2

3k^3 + k^2 - 4k

Explanation:

k * 3k^2 = 3k^3

k * k = k^2

k * -4 = -4k

3k^3 + k^2 - 4k
