Exponents

Simplify the following. Write your answer in the form where a is prime and b is an integer.

Uncertainty and Measurement

A standard ruler has an uncertainty of 0.5 mm.

Uncertainty

A notebook is measured with a standard ruler and its length is measured to be 11.4 cm. Therefore, we know that the length of the notebook is x, in the form: a < x < b, where a, b, and x are measured in cm. Write down the values of the real numbers a and b. Give your answer to two decimal places.
