Explanation:

You plug it into a calculator and it gives you that number. You have a calculator option on the left hand side that you can figure this out in as well.

Answer 2

For this case we must find the value of the expression shown:

`2 ^ {\sqrt {19}}`

When entering in a calculator, we have the following:

`\sqrt {19} = 4.35889894354`

When rewriting the expression we have left:

`2 ^ {4,35889894354} = 20,51914828`

Rounding:

`2 ^ {\sqrt {19}} = 20.5191`

Answer:

20.5191
