Answer: 
Step-by-step explanation:
You need to remember the Product of powers property:

Then, knowing this property, now you have to apply the Distributive property. So:

Finally, to simplify this expression, you need to add the like terms.
Therefore, you get that the product is:

You have to multiply 7 3/4 to 9.
First, turn 7 3/4 to an improper fraction which is 31/4.
Next, you multiply 31/4 to 9/1(same thing as 9) across from each other.
Then, you get the answer 279/4(31 x 9 = 279 ;4 x 1 = 4; 279/4).
Last divide 279 to 4 and get 67.75( .75 = 3/4 ; 69 3/4).
