It is 5, exactly as in the question.
The exponential notation of 0.00001 is 1.0 × 10-5
It means in powers as for example 5*5*5 in exponential notation is 5^3 which means 5 to the power of 3
6.75511e+5
21^5!
262,144 = 2.621440e+5
143,700 = 1.437000e+5
100,000 = 1e+5
4.565e+5
210,000 = 2.100000e+5
something like this: 5 to the power of 2 would be written as exponential notation like: 5²
3.35777e+5
262,144 = 2.621440e+5
