what is the square rot of 7
The Short answer is 2.64 or 3. The long answer is 2.6457513110645906.
That is also an approximation.
$${\sqrt{{\mathtt{7}}}}$$ is another irrational number - just like pi is. If you try to right it as a number, the digits will go on for ever, they will not terminate or recur. :)
