how do I simplify this?

[tezza]

= (($aa3*(1.075^$x3))+($aa3*(1.075^($x3+1)))+($aa3*(1.075^($x3+2)))+($aa3*(1.075^($x3+3)))+($aa3*(1.075^($x3+4)))+($aa3*(1.075^($x3+5)))+($aa3*(1.075^($x3+6)))+($aa3*(1.075^($x3+7)))+($aa3*(1.075^($x3+8)))+($aa3*(1.075^($x3+9))))

or another way of looking at it

= (
($AA3*(1.075^$X3))+
($AA3*(1.075^($X3+1)))+
($AA3*(1.075^($X3+2)))+
($AA3*(1.075^($X3+3)))+
($AA3*(1.075^($X3+4)))+
($AA3*(1.075^($X3+5)))+
($AA3*(1.075^($X3+6)))+
($AA3*(1.075^($X3+7)))+
($AA3*(1.075^($X3+8)))+
($AA3*(1.075^($X3+9)))
)

Hi.

=SUM($AA3*1.075^($X3+{0,1,2,3,4,5,6,7,8,9}))

=sumproduct(aa3*(1.075^(x3+(row(1:10)-1))))
