Question: typesetting in maple plots

Dear all,

 

I am trying to put labels for my axis and I use typeset to do that.

The code is:

plot(10^10*x, x = 0 .. 5,labels = ["x", typeset(10^10*Delta*z)],labeldirections = ["horizontal", "vertical"])

The problem is that  I get a label like below:

I mean it is not typed as 10^{10}, but 10000000000!!!

Can anyone help me in changing this to 10^10?
