We just started stuff like the power rule and things, I am not really understanding what to do here.. I will give you the list of Problems.. there is only 3 but I can't figure it out.. Please explain it to me!
- 2x^2+4
- 3x^5+6x^4+3x^2
- 2x^8+3x^5+4
Help differentiate those! :(

The power rule is quite difficult to learn and comprehend at first, however, it gets easier as time goes on!
These answers are:
1. 4x
2. 15x^4+24x^3+3
3. 16x^7+15x^4
The power rule states: b^a derivative is ab^a-1 .. Basically subtract 1 from the exponent and multiply the base b by a. :)
Any other questions feel free to ask.
