<h3>Answer: Choice C. </h3><h3>Division[ (4x^3+2x^2+3x+5)^2, x^2+3x+1]</h3>

=============================================================

Explanation:

It honestly depends on the CAS program, but for GeoGebra for instance, the general format would be Division[P, Q]

Where,

  • P = numerator = (4x^3+2x^2+3x+5)^2
  • Q = denominator = x^2+3x+1

As another example, let's say we want to divide x^2+5x+6 all over x^3+7 as one big fraction

We would type in Division[x^2+5x+6, x^3+7]

SOMEONE HELP PLS I NEED SOMEONE TO EXPLAIN STEP BY STEP IM SO CONFUSED
Minchanka [31]

Answer:

x = ln (33)

     ------------

      3 ln (2)

Step-by-step explanation:

2 ^ (3x) = 33

Take the ln of each side

ln ( 2 ^ (3x)) = ln  33

We know  ln ( a^b) = b ln a

3x ln (2) = ln 33

3x = ln 33

       ------------

           ln 2

Divide each side by 3

x = ln (33)

     ------------

      3 ln (2)
