It is 1.0*10^-5, almost exactly as in the question. Actually, the "^-5" should appear without the "^" and in superscript but the browser available to us is incapable of showing superscripts.

It is 3.25*10^10 in standard form or scientific notation
The way you wrote it is the standard notation. Standard notation means to write the number in its standard form. So, a number such as 150 is simply written as 150 in standard notation. The same applies to decimals. Unless you are not in the USA, in which case Standard form (also known as "standard index form" or "scientific notation") requires a single non-zero digit before the decimal point and a multiplier of a power of 10 which gets the decimal point back to where it was in the original number. To calculated the power of the ten count how many digits the decimal point needs to move; if it needs to move to the left make it negative: 0.00105 = 1.05 × 10^-3
0.02 in standard form is 2 x 10^-2. In scientific notation, standard form represents a number as a coefficient multiplied by a power of 10. In this case, 0.02 is written as 2 (the coefficient) multiplied by 10 raised to the power of -2 (since the decimal point is moved two places to the right to convert 0.02 to standard form).
