Interpreting Technical Specifications for Precision Instruments

Based on the Negative Exponent Definition, perform the following tasks to help the trainee:

  1. State the mathematical rule used to rewrite expressions with a negative exponent (the definition of a−na^{-n}).
  2. Identify the simplified fractional values for both the Focus Tolerance (4−24^{-2}) and the Signal Variance (10−310^{-3}).
  3. State whether these final simplified values are positive or negative quantities.
