Answer:
What is 9+10? It's 19
Step-by-step explanation:
Omg, thank you so much again!!!
You're da best!!!
Uhhh is this a real question because if it is I feel bad for the person who has to solve it lol
The answer would be -2,-1,0,1,2,3,4
Answer: 12/4
Step-by-step explanation: whole number = 3. given denominator = 4. 4/4 = 1. 1 times 3 = 3. 4 plus 4 plus 4 = 12. therefore answer is 12/4

now, that's just the derivative of the funtion inside ln()
bear in mind that
![\bf \cfrac{d}{dx}ln[f(x)]\implies \cfrac{f'(x)}{f(x)}](https://tex.z-dn.net/?f=%5Cbf%20%5Ccfrac%7Bd%7D%7Bdx%7Dln%5Bf%28x%29%5D%5Cimplies%20%5Ccfrac%7Bf%27%28x%29%7D%7Bf%28x%29%7D)
thus, let us give it the denominator to that
![\bf \cfrac{\frac{5(x+1)\sqrt{x+1}\left[ (x+2)-4(x+1) \right]}{2(x+2)^{11}}}{\sqrt{\frac{(x+1)^5}{(x+2)^{20}}}} \\\\\\ \cfrac{\frac{5(x+1)\sqrt{x+1}\left[ (x+2)-4(x+1) \right]}{2(x+2)^{11}}}{\frac{\sqrt{(x+1)^5}}{\sqrt{(x+2)^{20}}}} \\\\\\ \cfrac{5(x+1)\sqrt{x+1}\left[ (x+2)-4(x+1) \right]}{2(x+2)^{11}}\cdot \cfrac{\sqrt{(x+2)^{20}}}{\sqrt{(x+1)^5}}](https://tex.z-dn.net/?f=%5Cbf%20%5Ccfrac%7B%5Cfrac%7B5%28x%2B1%29%5Csqrt%7Bx%2B1%7D%5Cleft%5B%20%28x%2B2%29-4%28x%2B1%29%20%5Cright%5D%7D%7B2%28x%2B2%29%5E%7B11%7D%7D%7D%7B%5Csqrt%7B%5Cfrac%7B%28x%2B1%29%5E5%7D%7B%28x%2B2%29%5E%7B20%7D%7D%7D%7D%0A%5C%5C%5C%5C%5C%5C%0A%5Ccfrac%7B%5Cfrac%7B5%28x%2B1%29%5Csqrt%7Bx%2B1%7D%5Cleft%5B%20%28x%2B2%29-4%28x%2B1%29%20%5Cright%5D%7D%7B2%28x%2B2%29%5E%7B11%7D%7D%7D%7B%5Cfrac%7B%5Csqrt%7B%28x%2B1%29%5E5%7D%7D%7B%5Csqrt%7B%28x%2B2%29%5E%7B20%7D%7D%7D%7D%0A%5C%5C%5C%5C%5C%5C%0A%5Ccfrac%7B5%28x%2B1%29%5Csqrt%7Bx%2B1%7D%5Cleft%5B%20%28x%2B2%29-4%28x%2B1%29%20%5Cright%5D%7D%7B2%28x%2B2%29%5E%7B11%7D%7D%5Ccdot%20%5Ccfrac%7B%5Csqrt%7B%28x%2B2%29%5E%7B20%7D%7D%7D%7B%5Csqrt%7B%28x%2B1%29%5E5%7D%7D)

yeah, we can simplify the numerator only, since the denominator is a cubic
so...
