(6.2 * (10^(-5))) - (8.3 * (10^(-6))) = 5.37 × 10-5

Is there a rule that says that the lowest exponent will be in the result?

it is easy 8.3 * 10^-6 is also can be written as 0.83 * 10^-5 right ? see if u got that . SO now its is easy ! U take out the 10^-6 then u will have to simplify this (6.2-0.83) 10^-5 . I hope this step onwards u can carry out the calculation
