Answer 1

Answer:

3 x^2 thus B is the answer

Step-by-step explanation:

Simplify the following:

((3 x)/(x^3))/(x^(-4))

Multiply the numerator of (3 x)/(x^3 x^(-4)) by the reciprocal of the denominator. (3 x)/(x^3 x^(-4)) = (3 x^4)/(x^2):

(3 x^4)/(x^2)

Combine powers. (3 x^4)/x^2 = 3 x^(4 - 2):

3 x^(4 - 2)

4 - 2 = 2:

Answer: 3 x^2

Answer 2

Answer:

The answer to your question is 3x²

Step-by-step explanation:

                                    $3x \frac{1}{x^{-4} } x^{-3}$

Simplify the negative powers

                                    $3x \frac{x^{4} }{x^{3} }$

Simplify

                                          3x (x)

Result

                                          3x²
