First you need to write the numerical equation for the given:

When you will simplify this fraction, you can divide the expressions. Based on the law of exponents when you divide like terms with different exponents, you can subtract the exponents of the denominator from the numerator.
So if you will simplify the equation:

Subtract the following:
Exponents of a 7-4 and;
Exponents of b 8-4
Your answer should be
Answer:
your answer is B uwu have good day
Step-by-step explanation:
-3/4 is the answer.
First you must make all the denominators the same = 9/4 = 9/4, 6/1 (mulitply both sides by 4) = 24/4, 3/1 (multiply both sides by 4) = 12/4. So we come out with 9/4 - 24/4 +12/4.
Then solve. 9/4 - 24/4 +12/4 = -3/4
