For this case we have the following expression:
[tex]e ^ {\frac {1} {2}}[/tex]
We must evaluate the expression, then:
[tex]e ^ {0.5} =[/tex]
If we enter the expression in a calculator we have that the decimal form is given by:
[tex]1.64872127[/tex]
If we round the expression we have to:
[tex]e ^ {\frac {1} {2}} = 1.7[/tex]
The option that is closest is option A.
