Question

.

Answer 1

Oops...

\[\large \frac{3}{2x^2} + \frac{5}{4x^3}\] right?

there we go! lol

Answer 2

So we want a common denominator...what would that be here?

Answer 3

Well....hint* lol what would happen if you multiply the top and bottom of the first fraction by 2x? would you get a common denominator there?

Answer 4

So

\[\large \frac{3}{2x^2} \times \frac{2x}{2x} + \frac{5}{4x^3}\]

Would then become

\[\large \frac{6x}{\color \red{4x^3}} + \frac{5}{\color \red{4x^3}}\]

And looky there, we have our common denominator :D

Answer 5

Correct...and that will be the end of it...it wont simplify anymore after you add them

Answer 6

Not a problem!
