Solve (3^x+4^x)^x+10/(x+10)^10-x+pi

$$\frac { ( 3 ^ { x } + 4 ^ { x } ) ^ { x + 10 } } { ( x + 10 ) ^ { 10 - x } } + \pi$$

Evaluate

$$\left(x+10\right)^{x-10}\left(3^{x}+4^{x}\right)^{x+10}+\pi$$

Differentiate w.r.t. x

$$\left(x+10\right)^{-\left(10-x\right)-1}\left(3^{x}+4^{x}\right)^{x+9}\left(x\times 3^{x}\ln(3^{x}+4^{x})+x\times 4^{x}\ln(3^{x}+4^{x})+x\ln(x+10)\times 3^{x}+x\ln(x+10)\times 4^{x}+10\times 3^{x}\ln(3^{x}+4^{x})+10\times 4^{x}\ln(3^{x}+4^{x})+2\ln(2)x^{2}\times 4^{x}+\ln(3)x^{2}\times 3^{x}+x\times 3^{x}+x\times 4^{x}+10\ln(x+10)\times 3^{x}+10\ln(x+10)\times 4^{x}+20\ln(3)x\times 3^{x}+40\ln(2)x\times 4^{x}+100\ln(3)\times 3^{x}+200\ln(2)\times 4^{x}-10\times 3^{x}-10\times 4^{x}\right)$$
