Question

How do you evaluate `-( \frac { 1} { 2} ) ^ { 2} + 3+ 2`?

Answer 1

`19/4`

Explanation:

First, raise the fraction to a power of 2 by raising the numerator and denominator to that power
`1^2/2^2` = `-1/4`

Then add the numbers
`3+2=5`
so we get `-1/4+5`
Now add them
Write all numerators above the common denominator
`-1/4+20/4`

Add the numerator together
= `19/4`
