Answer:
No, Sorry.
Step-by-step explanation:
Since the bases are different, you'll have to change them even if they have a exponent or not. If you dunno how to make the denominators the same, just multiply the two by eachother.
Example) 1/2 - 3/4
![\frac{1}{2} - \frac{3}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20-%20%20%5Cfrac%7B3%7D%7B4%7D%20)
Multiply 2 and 4 together, and then multiply the 4 to the one also. Multiply 2 to four and also to the 3.
![\frac{4}{8} - \frac{6}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B8%7D%20%20-%20%20%5Cfrac%7B6%7D%7B8%7D%20)
The subtract from there.
![\frac{ - 2}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%202%7D%7B8%7D%20)
and then Reduce (if needed.)
![\frac{ - 1}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%201%7D%7B4%7D%20)
I have no idea tbh. I will try to find how to do it and help you!
Answer:
