why ? in order to make something into scientific notation , you have to make the number between 1 and 10. 0.001 isnt between 1 and 10 , so what you do i move the decimal and count. in this problem i moved it 3 times till it was behind the one and if you go to the left , it's a negative. therefore , i did 1 * 10^-3 ( im guessing you know why its 10 lol )
