All posible integer values of x = 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17.

So, the sum of all possible integer values of x is 147.

Hey Guest!, 

CPhill answered that question already in https://web2.0calc.com/questions/algebra_98880 

Whats the point of copying CPhill's answer? 

There is no need for the same work twice. How about next time do it yourself? :)

Thats because it doesn't! :p 

The answer to your question is 3 🍻

y = 1.13093

$Hint: 5^{3^{k+1}}+1=(5^{3^{k}})^{3}+1=(5^{3^{k}}+1)(5^{2⋅3^{k}}−5^{3^{k}}+1)$

If I am correct, h(t) = −t^2+ 8t + 10 so, the rock first reaches the height of 12m at 12 = −t^2+ 8t + 10 and by solving that quadratic we get, 

$T=4±\sqrt{14}$   

So, the rock first reaches the height of 12m at $4-\sqrt{14}$ which is aprox 0.25834261 seconds.

m*n^3^2/(2*m*n) Simplifies to     $(n^8)/2$
