Question

I am BEGGING for help right now. 32 POINTS!!!!!!!!! SAVE ME!!! ive asked this a few times now. Would you please help please?!?!

1. 3y to the power of 5 - 10 y to the power of 5
2. (5x-3y to the power of 5) to the power of 2
3. x to the power of 2 +6x-27
4. x to the power of 2 + x -30
5. x to the power of 2 -10xy +24y to the power of 2
6. 10x to the power of 2 +3x-4
7. 3x to the power of 2 -9x-30
8. d to the power of 2 +18d+81
9. d to the power of 2 +22d+121
10. t to the power of 2-81
Here are the bigger problems.
11. f (x)=9x to the power of 3+2x to the power of 2-5x+4 and g(x)=5x to the power of 3-7x+4. What is f(x)-g(x)? Show all work and in factored form.

Answer 1

1. 3y to the power of 25-50y
2. (5x-3y) to the power of 10
3. x to the power of 6x-25
4. x to the power of x - 28

There maybe another step here but I think you just simplify them to lowest terms.
