Hi I'm feeling very pathetic at the moment...! Can anyone tell me how to work out the following equation on a calculator? Thanks! PLEASE NOTE THE "6" is the power of 6 :-) So, here's the equation... X = 5220 (1.05) 6

Hello and welcome to MHB, AussieMel! :D

Do you have a graphing calculator? If so, you should be able to enter:

[m]5220*(1.05)^6[/m]

and press [ENTER] to get a decimal approximation.

If not, does your calculator have a button that looks like $$x^y$$?

If so, you may be able to enter the following to get a decimal approximation

1.05
$x^y$
6
[ENTER]
*5220
[ENTER]

You should find it is the repeating decimal:

[m]6995.2992440625[/m]
