## anonymous one year ago I dont understand how to determine the uncertainty when a number has the uncertainty implicitly.

1. anonymous

1) when the number is $5.3322*10 ^ {-5}$ , would the uncertainty be (1*10^-9) or (0.0001)?

2. anonymous

2) How to calculate the absolute uncertainty when there is an exponent. For example: $(-7.5899*10^{-6} ) *(22.62 \pm 0.01)$
