I need to solve the following equation

$3910935 = 734 (((i + 1)^9)/i)$

I need to know if its posible to solve for i.

Thanks

very difficult to solve by hand ... using technology, I get $i \approx 1.88$

there is also a negative solution.

attached is the graph of $y = 3910935 - \frac{734(x+1)^9}{x}$

zeros are solutions.

3. i = ~1.76335 ; 1.88 is way too high.

I think the solution was something like 1.12. I have to check that. But I was wondering if it was posible to leave the variable alone at one side of the equation.

5. No, not 1.12; it's 1.76335...

734 * 2.76335^9 / 1.76335 = 3910934.96976...

Make it 1.763350003 to get 3910935.00132...

By the way, you only need 1 set of brackets in your posted equation:
3910935 = 734(1 + i)^9 / i

6. Yes sorry. The number 3910935 is actually 3910.935 and for that number I Have i = 0,12 as an answer.

Huh? 734 * 1.12^9 / .12 = 16961.998... ; quite far from 3910.935 !

8. mmm Yes I have to re check the numbers on the problem.
