How to plot the string with power of ten as the exponential?

I want to plot a scientific title or legend label which is e^(x*10**b).

Here's an example:

import matplotlib.pyplot as plt

data = 5.55e10

plt.title('e$^{%.2e}$'%(data))

And, the actual output is:

The preferred output is:

Split the formatted string and format them again:

>>> val = 5.55e10
>>> base, power = f'{val:.2e}'.split('e')
>>> f'e$^{{{base}*10^{{{power}}}}}$'
'e$^{5.55*10^{+10}}$'

Output in matplotlib:
