If your device is not in landscape mode many of the equations will run off the side of your device (should be able to scroll to see them) and some of the menu items will be cut off due to the narrow screen width.

### Section 1.1 : Integer Exponents

2. Evaluate the following expression and write the answer as a single number without exponents.

$\frac{{{{\left( { - 2} \right)}^4}}}{{{{\left( {{3^2} + {2^2}} \right)}^2}}}$ Show Solution

There is not really a whole lot to this problem. All we need to do is the evaluations recalling the proper order of operations.

$\frac{{{{\left( { - 2} \right)}^4}}}{{{{\left( {{3^2} + {2^2}} \right)}^2}}} = \frac{{16}}{{{{\left( {9 + 4} \right)}^2}}} = \frac{{16}}{{{{\left( {13} \right)}^2}}} = \require{bbox} \bbox[2pt,border:1px solid black]{{\frac{{16}}{{169}}}}$

Remember that we need to do the evaluations inside the parenthesis in the denominator before we deal with the overall exponent that is on the parenthesis.
