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.)

$\frac{ - 1}{4}$
