### Four 4's

Using arithmetic combinations of four 4's express the numbers from 1 to 10.

You must use all four 4's for each number.

You may combine the 4's using the arithmetic operations +, -, * (multiplication) and / (division).

You are also allowed to use sqrt (square root) (e.g. sqrt(4)=2, sqrt(4/4)=1).

You do not need to use concatenation (e.g. 44), decimal places (e.g. 4.4), factorials (e.g. 4!), or trig functions such as sin or cos.
