5 x 10^3
1.6 × 10-8 written in standard notation is 0.000000016
in standard form? 2.4*10^5 stick the decimal point between the 2 and the four: the first two digits, then how many places would you have to move the decimal to get back to the original number? this is equal the a multiple of ten each time, so we say, in this case, you would have to move the decimal 5 places to the right, so its *10^5 where ^ indicates that its a raised to the power sign, and * indicates we multiply. For example x squared is x^2 in this notation, and the only reason I'm having to use it, is because there is no way for my keyboard to write common maths easily. Using ^ and * in this answer is not part of the standard form notation, and you would just write it out normally: 2.4 times 10 to the power of 5. This notation is called standard index form.
