    what does this symbol mean

    un=5*(0.4)^(n-1)


    can someone please how is this written manually, i mean the ^ symbol and the *, are these just pc terms, or do they remain the same when written manually, thanks

    You can use LaTeX tags to show symbols.
    [tex]u_n=5\cdot (0.4)^{n-1}[/tex] gives u_n=5\cdot (0.4)^{n-1}.
