1. loga (a/ Square root x) - log a (square root of ax)

2. 120 (ln 5 square root x^3) + ln (3 square root of y^2) - ln (4 square root of 16z^5)0

----

Btw in NUMBER 2, the 5 in the square root of x^3 goes in the left top, and the 3 and the 4 too.


thanks

The annual cost of production of a ton of a chemical is given by the following formula, where x is the number of tons per year produced.

Cost per ton = 1,000,000 / x + 100 + x

can you find the value of x for which the cost per ton is a minimum, and the cost per ton for this value of x.

My teacher gave the entire class a huge packet to complete because the class did bad on the test (I did well). I dont have enough time to finish this and all of my other HW, can you do some of the following.
State whether the critical point is maximum, minimum, or point of inflection

1. y= x^2 - 6x +1; x=3
2. x^2 - 2x -6; x=1
3. x^4 +3x^2-5;x=0
4.x^5-2x^3-2x^2;x=0
5.x^3+x^2-x;x=-1
6.2x^3+4; x=0

if you can do atleast one of them that would be good. I still have more HW to finish before the fight (Mayweather Hatton)
