1. The product of 23 times f. 3. Five times m to the second power plus 2 or the product of four and m to the second power plus two. 4. four times n to the second power divided by 7 or the product of four and n to the second power divided by 7. 2. The difference of 4 times d to the third power and 10. I hope this helps. I'm not positive I'm right, but I might be.
