To convert into scientific notation, all you have to do is move decimal places basically... You need one number in front of a decimal and the rest behind it, followed by 10^(number of places the decimal moved). If you move the decimal left, the exponent is positive, if you go right, it's negative.
So, 15400, you would have 1.54 X 10^4, since we moved the decimal 4 places to the left.
0.00033 would be 3.3 X 10^(-4) since we moved the decimal 4 places to the right.
2050 is 2.05 X 10^3
0.000015 is 1.5 X 10^(-5)
Hope this helps! :-)

15400.00 mm3 = 1,54x10^4 mm3
0.00033 kg = 3,3x10^-4 kg
The idea is that you move the decimal point to the left or right until there is only one digit to the left of it. Let's call this number a number "A". Then you count how many ciphers you jumped (n) and you simply write it down in form of "A times 10^n" (ten to the power of n). If you move decimal point to the right, n gets a minus sign (is negative), and if you move decimal point to the left, n is a positive number.
2050ml = 2,05x10^3ml
0.000015 = 1.5x10^-5
I hope this helps you to understand conversions.
Have a nice time.
