Question

Can the exponent in the denominator be subtracted from the exponent in the numerator when the based are different? Explain

Answer 1

No, Sorry.

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

`(1)/(2) - (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.

`(4)/(8) - (6)/(8)`

The subtract from there.

`( - 2)/(8)`

and then Reduce (if needed.)

`( - 1)/(4)`
