Do you want to know how to open the calculator on the device you were typing this?
And are you using a comma as separation sign for 0.2 = 1/5?

You may have already learned how. Your base is a decimal number and your exponent is a natural number.
(0.212765957)^2
(212765957*10^-9)^2
(212765957)^2*(10^(-18))
but really, the easier way as already said, use a calculator.******
(0.212765957)^2
(212765957*10^{-9})^2
(212765957)^2*(10^{-18}), that negative eighteen is supposed to be an exponent.
Mod note: Fixed the exponent.
symbolipoint note: Thanks, Mod; now I fixed the negative nine exponent also.
