Is there a command / Syntax line i can use to get an exact number when calculating equations?

When i input this command "solve(1295.28=800*(1+x)^9,x)" i get many fraction solutions.
It is really annoying i'm just getting my straight number i need and i need to then copy paste one of the fractions to get the number.
I tried evalf like in Maple and numbervalue just for luck, but no luck.

Would really help making school math go by faster :D
Thanks for your time

EDIT:
Also does it with this equation.
solve(1545.62=1200*(1+0.015)^x,x) 
And you can't even use the output to get a numerical value... This is really annoying.

I've no idea why this works!!

For your other equation you need to do some manipulation first:
