    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}

    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}

    The subtract from there.

     \frac{ - 2}{8}

    and then Reduce (if needed.)

     \frac{ - 1}{4}
